The Armenian Catholic church of Surp Asdvadzadzin (Immaculate Conception of the Blessed Virgin) is in Meşrutiyet Mahallesi about four hundred meters southwest of the iskele, on Mehmetçık Sokağı near its intersection with Kadıyoran Caddesi. This is a large basilica in the neoclassical style of the Italian Renaissance, built in the years 1856-58.

Büyükada Anadolu Club founded in 1906 as the Prinkipo Yacht Club. Notable guests have included Atatürk and Ismet Inönü as well as foreign heads of state: Elefterios Venizelos, Prime Minister of Greece (1924); King Amanullah Han of Afghanistan (1930); King Carol of Romania and Madame Lupescu (1933); General Metaxas, the Greek dictator (1936); Shah Riza Pahlavi of Iran (1964); and Nikolau Ceausescu, the Romanian dictator (1976). When Atatürk visited the club he stayed in Room 25, which is preserved as it was in his time. In the garden of the club there is a monument to Atatürk, dedicated in 1981 to mark the centenary of his birth. The club cannot be visited, but one can observe the beautiful buildings and grounds from the gateway.
