History
Kite Castle is a Byzantine fortress in Türkiye, located in present-day Ürünlü in Bursa’s Nilüfer district. Known as Kitai during the Byzantine period, it stood in Bithynia, the historical region of northwestern Anatolia that included Bursa, İznik, and the Sea of Marmara. The castle protected the logistical route between Prusa, the Byzantine-era name for Bursa, and Apollonia, now Gölyazı.
Byzantine Administrative and Defensive Role
During the Byzantine period, Kite served as a strategic administrative and defensive center. It was also a tekfurluk, the territory or administrative center governed by a tekfur, a locally appointed Byzantine ruler or governor in Anatolia. Its position made it an important obstacle to the Ottoman advance toward Bursa.
The Ottoman Conquest
After the Ottoman victory at the Battle of Koyunhisar in 1302, the Ottomans blockaded İznik and Bursa and turned against the surrounding castles of Kite, Kestel, and Atranos, now Orhaneli. Their aim was to sever Bursa’s connections with the outside world. The Kite tekfur joined the alliance that opposed the Ottomans at the Battle of Dimbos in 1303. Following the alliance’s defeat, he withdrew to Kite Castle. Forces commanded by Osman Gazi, founder of the Ottoman dynasty and leader of the early Ottoman expansion in Byzantine Anatolia, besieged and captured the fortress shortly afterward. The Aşıkpaşazade History states that the Kite tekfur was executed in front of the castle as a warning to other regional tekfurs.
Ottoman Military Use
Following its conquest, Kite Castle remained part of the Ottoman military organization. Its functions included serving as a military base and administrative center, with a müstahfızan unit, or group of castle guards, stationed there. A 1660 register lists Kite among the castles of the Hüdavendigar Sanjak, the Ottoman administrative district centered on Bursa, and records timar assignments for its guards. A timar granted state revenue, often from agricultural land, in return for military or administrative service.
An Ottoman berat, or official charter, issued in 1732 refers to Mustafa as a long-serving member of the Kite Castle personnel. This reference confirms that military staff continued to serve at the fortress over an extended period. The castle was gradually damaged and had become a ruin by the present day.

Fortress Layout and Construction
Kite Castle was a rectangular, flatland fortress of castrum type, meaning a fortified military camp or stronghold arranged around a regular plan. It stood on level ground rather than on a steep hill, unlike other castles in the Bursa Plain. This setting created a defensive disadvantage, so the walls are thought to have been made thicker and higher than contemporary standards. Their masonry used alternating courses of brick and rubble stone, a construction technique characteristic of Byzantine building.
Surviving Walls and Reused Materials
The main body of the castle has largely collapsed, but foundations and sections of wall remain visible at various points in Ürünlü. Materials removed from the castle walls were reused in the historic Kite Bathhouse in the village. The surviving ruins are distributed within the village and preserve parts of the fortress’s former physical presence.
