Martyrs' Lane is also home to Baku Turkish Martyrs' Memorial, a large memorial to the 1,130 Turkish troops who were killed while fighting Bolshevik and Armenian forces during the Battle of Baku in 1918. Next to the memorial there is a martyrs mosque, also built by Turks. The memorial contains a hexagonal block clad in red granite; each face contains a pure white marble crescent-star, based on those in the Turkish national flag. It was unveiled by the former Turkish president Süleyman Demirel and the Azerbaijani president Heydar Aliyev at a formal ceremony in September, 1999.
