Around town are Russian belle époque mansions and other examples of Baltic architecture. On Ordu Caddesi are the Health Directorate Building (1907), with columns and floral motifs; the yellow-and-white Old Governor's Mansion (1883), where the Treaty of Kars was signed in 1921; and the Gazi Kars Anatolian High School , occupying a late-19th-century winter mansion. The Fethiye Camii , a converted 19th-century Russian Orthodox church, stands majestically south of the centre.
