Beylerbeyi, built under Sultan Abdülaziz by another member of the talented Balyan family of architects in the European style of Dolmabahçe, was the second palace to be built on the Bosphorus and served as a summer residence and guest quarters for bey (dignitaries) during their visits to the city. The shah of Iran and the king of Montenegro were guests here as well as the French Empress Eugénie, who admired the palace so much that she had the design of the windows copied on the Tuilleries Palace in Paris. It's a bit dusty, and not as grand as Dolmabahçe, but worth a visit if you're on the Asian side and looking for a diversion.
Beylerbeyi, which replaced Abdülmecid's previous palace, was completed in 1865 on a less extravagant scale than the one on the European shores, employing only 5,000 men to build it. Although less grand and weathered by time, Beylerbeyi has some features worthy of a visit, not least of all the terraced garden of magnolias at the base of the Bosphorus Bridge. The monumental staircase to this marble palace is fronted by a pool and fountain which served as much to cool the air as to look pretty, and the floors are covered with reed mats from Egypt that act as insulation against dampness. The grounds contain sumptuous pavilions and kiosks, including the Stable Pavilion, where the imperial stud was kept.
Ironically, Abdülhamid II spent the last 6 years of his life admiring Dolmabahçe from the other side of the Bosphorus, having been deposed and kept under house arrest here until his death in 1918.
