The town of Brússa having been built towards the North on natural rocks has no ditch, but on the side of the head fountain (Búnár-báshí) and the quarter of the Mills, it has a deep one, which at the time of the Asiatic rebellions of Kará Yazijí, Kallender and Sa’íd Arab was filled up. Some of the stones of the walls are of the size of the cupola of a bath, and some bear Greek inscriptions on them. The town is protected against southerly and easterly winds from its being situated at the foot of Mount Olympus. The houses have a northern aspect and look over the plain of Filehdár. The fortress, the circumference of which is eleven thousand paces, has six thousand battlements, sixty-seven towers, and four gates, viz. the gate of the head fountain, the prison-gate, the hot-baths’-gate to the west, and the gate of the fishmarket. This stronghold was besieged more than once by the Seljúkians, who came with an army of twenty thousand men; the siege lasted between seven and eight months, the besiegers retiring only on the approach of winter. Osmán the founder of the Ottoman dynasty besieged it three times, but was compelled on the last occasion by an attack of the gout to retire to Iconium. He sent his son Orkhán with Sheikh Hájí Begtásh, who renewed the siege, and built two great towers, one at the side of the hot-baths (Kaplijah), and the other on the side of the head fountain (Búnár-báshí), which took seven months to complete. Orkhán posted himself at the hot-bath, his nephew Timúr-beg, at the head-fountain, and Yalabánjik-beg at the mountain’s side. It surrendered in 722 (1322) after a year’s siege, and Osmán died at the moment he received the news. Orkhán his successor entered Brússa with Hájí Begtásh, there fixed his residence, and buried his father’s body in the castle. Osmán conquered seventy towns during the lifetime of his father Ertoghrúl. His first conquest was in Kojá-Ilí by Akcheh Kojá. Near Nicæa at the castle of Wáilakabád, he begat his son Orkhán on Sheikh Edebáli’s daughter, who was related to the prophet, so that the Ottoman Sultáns are Seyyids or Sherífs on the mother’s side. Sheikh Túrsún their first divine was a relation of Sheikh Edebáli, and said the first prayer from the pulpit in Sultán Osmán’s name. Brússa soon became populated by mussulman colonists from all quarters. _Description of the Buildings of Brússa._
