The centre of the old city is a semicircular Neoclassical square with the Tuscan column of cast iron (1805–11), commemorating the centenary of the Battle of Poltava and featuring 18 Swedish cannons captured in that battle. As Peter the Great celebrated his victory in the Saviour church, this 17th-century wooden shrine was carefully preserved to this day. The five-domed city cathedral, dedicated to the Exaltation of the Cross, is a superb monument of Cossack Baroque, built between 1699 and 1709. As a whole, the cathedral presents a unity which even the Neoclassical belltower has failed to mar. Another frothy Baroque church, dedicated to the Dormition of the Theotokos, was destroyed in 1934 and rebuilt in the 1990s.
