Faş Castle

Faş Kalesi was located at the strategic site now known as Poti. Situated on Georgia’s Black Sea coast between Batum and Anakara, at the point where the Rioni (Faş) River flows into the Black Sea, the fortress has historically been a critical node, enhancing the importance of ports as much as the land corridors of the Caucasus, which functioned as a “Black Strait” between Asia and Europe. Due particularly to the Rioni River’s extension deep into Georgia, Faş emerged as a strategic center accessible by both sea and river. For the Ottoman Empire, it held great significance as a measure against piracy in the Black Sea and as a defensive outpost against Russian threats from the Caucasus.

Geographical Location and Strategic Importance of Faş Kalesi

Faş Kalesi, known today as Poti, is located on Georgia’s Black Sea coast between Batum and Anakara. It lies approximately 100 miles from Batum, at the mouth of the Rioni (Faş) River where it meets the Black Sea. Geographically, the Rioni River, which originates from the Open-baş and Megrelian regions and collects the waters of Cürle, Gürle, Aygır and Faş before emptying into the Black Sea, formed a natural harbor and has held major strategic importance throughout history.

The Caucasus region, functioning as a “Black Strait” between Asia and Europe, had limited land passages such as Avar, Daryal and Derbend, which increased the strategic value of its ports. In this context, Faş rose as a strategic center not only because of its excellent harbor but also due to the navigability of the Rioni River, which extended deep into Georgia. The river served as a vital artery for commercial and military movements within Georgia’s interior.

Faş Kalesi played a pivotal role for the Ottoman Empire in combating widespread piracy in the Black Sea. The fortress served as a vital base for ensuring security in the Black Sea and protecting trade routes. Simultaneously, it functioned as an advanced defensive line against potential Russian threats from the Caucasus and as an important forward garrison to consolidate Ottoman authority in the region. This strategic position made Faş Kalesi an indispensable element in the Ottoman Empire’s efforts to maintain and expand its influence in the region by both sea and land.

Transition of the Region to Ottoman Control

The eastern Black Sea and Caucasus region has been a strategic area since the foundation of the Ottoman Empire, inhabited by various Georgian principalities and local elements. This region held great importance for the Ottomans due to its trade routes across the Black Sea and its relations with Russia.

Conquest Process and Administrative Organization

Ottoman dominance in the region began to take shape with the Treaty of Amasya (1555). This treaty divided Caucasian territories between the Ottoman and Safavid Empires, with Georgia split between Ottoman and Safavid spheres of influence. However, this arrangement did not fully secure Ottoman influence in the region. Full transition to Ottoman control accelerated during the reign of Murad III, particularly with the large-scale Caucasus campaign led by Lala Mustafa Pasha in 1578. As a result of this campaign, numerous Georgian principalities came under Ottoman sovereignty, and Faş and its surroundings were incorporated into Ottoman territory.

Following its capture, Faş was established as a sanjak and attached to the Trabzon Eyalet. The Sanjak of Faş played a central role in the region’s administrative and military organization. A sanjakbey was appointed to oversee the construction and defense of the fortress, as well as to establish Ottoman administration and ensure security in the region.

Piracy in the Eastern Black Sea and Ottoman Countermeasures

The Black Sea, particularly during the Ottoman period, was a region of intense piracy carried out by Cossacks and local elements. This activity negatively affected maritime trade and posed a threat to Ottoman coastal settlements. One of the primary motivations for constructing Faş Kalesi was to combat these piracy activities. The fortress served as a base for the Ottoman navy along the eastern Black Sea coast and constituted a crucial measure to control pirate movements. Additionally, the collection of customs revenues and the maintenance of public order were among the fortress’s functions. The construction of Faş Kalesi and its subsequent strengthening formed an essential part of the Ottoman strategy to consolidate its authority and ensure security in the Black Sea.

First Construction of Faş Kalesi (1579)

The first construction of Faş Kalesi took place in 1579, based on the Ottoman Empire’s strategic needs in the region. The fortress was built atop the ruins of an earlier structure, indicating that the area had been considered militarily significant in prior periods.

Decision to Build and Objectives

The primary objectives of constructing the fortress were to combat piracy in the Black Sea, collect customs revenues, and strengthen Ottoman authority in the region. Following Lala Mustafa Pasha’s Caucasus campaign and the incorporation of Faş as a sanjak, the construction of a strong fortress became essential. The fortress became a symbol of Ottoman military and administrative presence in eastern Black Sea.

Construction Process and Materials Used

Construction began on 26 July 1579. The building process took into account the region’s geographical conditions and available technological capabilities. The initial fortress was constructed primarily from wood and reeds—locally available and easily accessible materials. The fortress walls were raised on sturdy wooden piles, filled with reeds. This construction technique enabled rapid completion but resulted in structural limitations in durability. Inside the fortress, essential structures such as a mosque, bathhouse, storeroom, and gunpowder magazine were also built.

Condition of the First Fortress and Need for Repair

The use of wood and reeds led to rapid deterioration of the fortress. Especially due to the region’s humid climate and the river’s influence, the foundations and walls gradually weakened. Subsequent records indicate that the fortress required frequent repairs and even complete reconstruction, revealing the weaknesses of the original structure. This first fortress, completed in 1579, is recorded as the Ottoman Empire’s first serious military investment in Faş, but it soon proved inadequate and necessitated a more durable structure.

Reconstruction and Expansion of Faş Kalesi (1724–1729)

Approximately 150 years after its initial construction, a comprehensive reconstruction and expansion of Faş Kalesi took place between 1724 and 1729. The original structure’s use of fragile materials such as wood and reeds had led to its deterioration and inability to meet strategic requirements. This situation made it necessary to rebuild the fortress using stone and more durable materials.

The decision to reconstruct the fortress was driven primarily by the increasing Russian threat in the region and the Ottoman Empire’s need to strengthen its Black Sea defense strategy. Detailed surveys and planning were conducted prior to construction. These studies determined the dimensions, architecture, and internal layout of the new fortress. In March 1724, construction began after the chief architect personally surveyed the site and selected the optimal location, preparing detailed plans.

The reconstructed Faş Kalesi was built entirely of stone to ensure greater durability. Designed with a rectangular plan, its dimensions were 150 x 120 zira (approximately 114 x 91 meters). Wall thicknesses were 7 zira (approximately 5.3 meters) at the base and 4 zira (approximately 3 meters) at the top. The fortress was surrounded by four large towers and strong ramparts extending to the riverbank. Inside, as in the previous structure, essential buildings included a mosque, bathhouse, storeroom, gunpowder magazine, armory, various warehouses, quarters for personnel, and food depots. These structures were arranged to meet both military and living needs.

Procuring materials such as stone and timber for construction required significant logistical planning, given the challenges of the period. The report submitted by Abaza Bey Arslan Bey provided crucial details regarding the quarrying and transportation of stone and timber. The report specified that stone from the Fişta and Lise streams would be transported by sea to Faş, and detailed the labor and equipment required for timber cutting.

Construction began in March 1724 and was carried out with large-scale organization. A substantial budget was allocated for the project, employing skilled craftsmen brought from Istanbul alongside qualified and unskilled local laborers. Major preparations were made for material procurement; essential construction materials such as stone, lime, and timber were supplied in large quantities. Lime was sourced from quarries in Georgia’s interior, while stone was extracted from mountains near the Fişta and Lise streams.

Initial Preparations and Personnel Deployment

Significant preliminary work was conducted before construction began to gather materials and organize labor. Key officials including the chief architect, fortress commander, and steward were appointed to lead the project.

Recruitment and Payment of Laborers (Neferat)

A large number of workers were recruited for the fortress construction. These included stone masons, stone breakers, woodcutters, lime kiln workers, basket makers, and porters. Workers were gathered from various parts of the region and paid daily wages. For example, master stone masons received 15–16 akçe per day, while other laborers received lower rates.

Transportation and Logistics

Various transportation methods were used to move construction materials. For land transport, specially constructed ox carts with wheels were employed. For maritime transport, large vessels called “Tonbaz” and smaller boats were built. These ships were primarily used to carry heavy and bulky materials across the Black Sea.

Procurement of Ammunition and Provisions

Continuous supply of ammunition and provisions was maintained for the workers and soldiers during construction. This formed a critical component of the project’s logistical planning, ensuring the availability of resources necessary for both the construction and future defense of the fortress.

The Role of Faş Kalesi in Ottoman-Russian Relations

Due to its geographical position, Faş Kalesi played a pivotal role in the strategic rivalry between the Ottoman Empire and Russia. From the 18th century onward, Russia’s expansionist policies toward the Black Sea and Caucasus turned Faş Kalesi into a persistent flashpoint between the two powers.

Throughout the 18th century, Russia’s efforts to increase its influence in the Black Sea began to directly threaten Ottoman security in the region. Russian pressure on Azov and Crimea compelled the Ottomans to strengthen their fortifications along the eastern Black Sea coast. In this context, Faş Kalesi was viewed as an advanced garrison and a barrier to Russian influence in the Caucasus. The fortress became a vital component of regional defense against potential Russian attacks by sea and land.

Aware of the fortress’s strategic importance, the Ottomans continued repair efforts into the final quarter of the 18th century. The activities of Halil Pasha between 1780 and 1783 included significant steps to maintain and enhance the fortress’s defensive capacity. However, sources also note administrative problems during this period, including issues with military discipline, troop numbers, and salary payments, which occasionally undermined the fortress’s defensive effectiveness.

The threats faced by the fortress were not solely from Russia; Georgian principalities also occasionally launched attacks against it. In 1784, a major Georgian assault on Faş Kalesi served as a critical test of the fortress’s defensive capacity and the resilience of Ottoman troops. The attack was repelled, but it once again underscored the necessity of constant vigilance.

One of the most critical roles of Faş Kalesi in Ottoman-Russian relations emerged during the Ottoman-Russian War of 1806–1812. During this conflict, the fortress became a key symbol of Ottoman resistance on the Caucasus front. It served as a vital defensive point to halt Russian advances along the Black Sea coast and prevent their penetration into inland regions. Throughout the war, the fortress endured Russian sieges and assaults and managed to hold out for an extended period. This resistance helped the Ottomans sustain their military presence in the region and buy time for their broader struggle in the Caucasus. The military and logistical importance of Faş Kalesi during this period is regarded as one of the factors influencing the course of the war. However, by the war’s end, the overall deterioration of Ottoman military conditions and Russian pressure determined the fortress’s fate.

The Loss of Faş Kalesi

The loss of Faş Kalesi from Ottoman control was formalized by the Treaty of Edirne (1829), signed after the Ottoman-Russian War of 1828–1829. This treaty imposed heavy consequences on the Ottoman Empire and resulted in the cession of numerous strategic territories to Russia. Under the treaty’s terms, Faş Kalesi was among the territories transferred to Russia.

The cession of the fortress significantly weakened Ottoman influence in eastern Black Sea and the Caucasus. The loss of Faş strengthened Russia’s position along the Black Sea coast and enabled it to exert greater control over military and commercial activities in the region. This created a serious gap in the Ottoman defensive line and diminished its ability to resist future Russian advances.

The transfer of Faş Kalesi to Russia was not merely the loss of a fortress or territory; it also marked the decline of Ottoman influence over maritime security and trade in the Black Sea and the weakening of ties with Muslim populations in the Caucasus. Thus, Faş Kalesi entered history as a concrete example of the Ottoman Empire’s territorial losses and its military and diplomatic weaknesses in the face of Russia.
