Nilüfer (District)

Nilüfer is a central district of Bursa Province in Türkiye’s Marmara Region, distinguished by its urban and economic development. It is located approximately 10 kilometers west of Bursa’s city center. To the east of the district lies Osmangazi, to the west Karacabey and partially Mustafakemalpaşa along with Lake Uluabat, to the north Mudanya, and to the south Orhaneli. The total area of the district is 423,181 decares (approximately 423 km²). Its elevation ranges from an average of 100 to 150 meters above sea level. Due to its geographical position and development trajectory, Nilüfer has become one of Bursa’s primary settlement centers expanding toward the west.

History

The district of Nilüfer derives its name from the Nilüfer Creek, which flows through it; the creek itself is named after Nilüfer Hatun, the wife of Ottoman Sultan Orhan Gazi. The region has been inhabited since prehistoric times, as evidenced by archaeological excavations at sites such as Aktopraklık Höyüğü in Akçalar and Tepecik Höyüğü in Alaaddinbey Mahallesi. These findings date the history of Nilüfer back to the 6th millennium BCE.

During antiquity, the district gained prominence through settlements such as Gölyazı (Apollonia ad Rhyndacum), which served as a religious and commercial center during the Roman and Byzantine periods. Places like Misi (modern-day Gümüştepe) also held significance in the context of early Christianity. After its conquest by Orhan Gazi in 1316, the region was incorporated into Ottoman rule and fortified with strategic castles.

With Bursa’s elevation to metropolitan municipality status in 1987, Nilüfer was established as one of three central districts alongside Osmangazi and Yıldırım. Since then, urbanization has accelerated significantly through large-scale housing projects.

Administrative Structure

Nilüfer District comprises a total of 64 administrative units: 42 neighborhoods and 22 rural neighborhoods (former villages). Notable neighborhoods within the district include Ataevler, Altınşehir, İhsaniye, Özlüce, Görükle, and Kayapa. Rural areas include villages such as Ayva, Dağyenice, Fadıllı, and Üçpınar. Local governance and public services are managed by the Bursa Metropolitan Municipality and Nilüfer Municipality.

Tourism and Cultural Heritage

Gölyazı

Gölyazı is situated on a peninsula and island area on Lake Uluabat, approximately 42 kilometers west of Bursa. Its ancient name, Apollonia ad Rhyndacum, dates back to the 6th century BCE. The settlement developed during the Roman and Byzantine eras and features layered architectural remains including the Temple of Apollo, an ancient theater, city wall fragments, Byzantine churches, and Ottoman-era mosques and bathhouses. The peninsula and its surroundings are protected as a SIT (Special Environmental Protection Area). The approximately 750-year-old “Ağlayan Çınar” (Weeping Plane Tree) in the village square is under special protection.

Following the 1924 population exchange, Gölyazı became home to Turkish settlers from Thessaloniki, leaving traces of a Turkish-Rum cultural blend. The local economy relies on agriculture, fishing, and tourism. The shallow, reed-filled structure of Lake Uluabat creates unique natural beauty. Visitors enjoy fish meze, lake tours, and sunset views from Zambak Tepesi. The site is easily accessible via the Bursa–İzmir highway. Gölyazı is a significant cultural and tourism center, notable for its historical richness and natural environment.

Gümüştepe (Misi)

The former name of Gümüştepe is “Misi.” Misi was one of the settlements established by the Misians who migrated from Thrace to Anatolia in 1816 BCE. Christian monks arrived in the region in 183 CE and conducted missionary activities, including theological debates. It is believed that a copy of the Bible was buried in the Misipoli Monastery; however, the monastery was looted in the 1950s.

In 1316, Orhan Gazi captured Misi and constructed fortresses to besiege Bursa. Some sources indicate that Misi briefly served as a temporary capital. Its importance declined after Bursa’s conquest in 1326.

Located at a sharp gorge of the Nilüfer Creek, Misi has historically been a strategic transit point along the Silk Road.
