Sarıkaya Roman Bath

Sarıkaya Roman Bath is a monumental thermal bath structure dated to the Roman Empire period, located in the Sarıkaya district of Yozgat province in Türkiye’s Central Anatolia Region. The structure was constructed directly in relation to a natural hot spring source and represents one of the most significant examples of Roman bath architecture in Anatolia. Ancient sources and modern research indicate that the site and settlement were referred to by the names Aquae Sarvenae, Therma, and Basilica Therma.

Geographical Location and Natural Environment

The Sarıkaya Roman Bath is situated in the Kaplıca neighbourhood, which is currently part of the Sarıkaya district centre. The structure was built on the area where the natural thermal spring emerges to the surface. It is noted that the water from the source still emerges at a temperature of approximately 48 °C today. This natural characteristic indicates that the building was planned during the Roman period as a thermal centre.

Historical Background and Nomenclature

Sarıkaya and its surroundings lie within the intersection area of the ancient provinces of Cappadocia, Galatia, and Bithynia-Pontus. Different names for the region and the bath have been recorded in ancient and medieval sources. In the literature, the name Aquae Sarvenae emphasizes the region’s thermal properties, while the names Therma and Basilica Therma are associated with the administrative and religious status of the settlement during the Roman and Byzantine periods.

It is stated that during the Byzantine period, the name Basilica Therma became widespread, as the settlement functioned as a bishopric centre and was located along important military routes. During the Ottoman period, the settlement and its surrounding bath were referred to by names such as Terzili Hamamı, Ilısu Karyesi, and Uyuz Hamamı.

Architectural Features

The Sarıkaya Roman Bath reflects the characteristic features of Roman bath architecture. The most prominent architectural element surviving to the present day is the monumental western façade. This façade is arranged in two stories and enriched with arched openings, pilasters, and ornamental architectural elements. Corinthian-capital pilasters, architraves, and frieze decorations on the façade are particularly striking.

Excavations and architectural studies have revealed that the building’s plan includes spaces arranged according to different temperature zones, as well as areas heated by a hypocaust system. The hypocaust system operated by channeling hot water and steam through cavities beneath the floor to warm the interior spaces.

Thermal Function and Usage

The Sarıkaya Roman Bath functioned as a thermal bath based on its natural hot spring source. It is well known that Roman thermal baths were not used solely for hygiene but also served as centres for health, therapy, and social interaction. The bath in Sarıkaya is likewise understood to have operated within this multifunctional framework.

The large pools (natatio) within the bath complex were elements supporting its communal use and therapeutic functions.

Archaeological Research and Findings

The first scientific observations at the Sarıkaya Roman Bath were conducted in the early 20th century, while comprehensive excavation and cleaning works were carried out between 2010 and 2015 under the supervision of the Yozgat Museum Directorate. As a result of these studies, architectural remains and archaeological finds dating to the Roman, Byzantine, Seljuk, and Ottoman periods were identified.

Architectural elements uncovered during the excavations include marble flooring, columns, arches, pools, and remnants of the hypocaust system. Additionally, coins recovered from the site indicate that the bath was in use at least until the 2nd century CE.

Current Status and Conservation

Today, the Sarıkaya Roman Bath holds the status of a protected immovable cultural heritage site and functions as an archaeological area open to visitors. The monumental façade and thermal pools are particularly prominent features, and the site is regarded within the framework of cultural heritage.
