St. Alexander Nevsky Cathedral is an orthodox cathedral situated on Toompea Hill. The cathedral was built in 1900. During this period Estonia was part of the Russian empire. Nowadays it is considered to be Estonian’s main Russian Orthodox cathedral.

The well-maintained cathedral is one of the most monumental examples of Orthodox sacral architecture in Tallinn. The cathedral was dedicated to the Prince of Novgorod, Alexander Yaroslavich Nevsky, who led the famous Battle of the Ice at Lake Peipsi in 1242, which halted the German crusaders’ eastward advance. The cathedral is richly decorated with a mixed historic style. The interior is rich in mosaics and icons. The base of the building is made from Finnish granite. In the five onion domes there are gilded iron crosses. Inside are three gilded, carved wooden iconostases, along with four icon boxes. The icons of the iconostasis and icon boxes were painted in St. Petersburg on copper and zinc plates. The windows are decorated with stained glass. To add, the cathedral is decorated and has eleven bells, the largest of which weighs approximately 16 tons. St. Alexander Nevsky Catherdal has three altars, with the northern altar dedicated to Vladimir I and the southern to St. Sergius of Radonezh.
