Visit of the Alexander Nevsky Cathedral. Alexander Nevsky Cathedral is Tallinn’s largest and grandest cupola cathedral. The large, richly decorated Orthodox Church, in mixed historicist style, was built on Toompea Hill in 1900, when Estonia was part of the Russian tsarist empire. The architect of the church was Mikhail Preobrazhenski from St. Petersburg. The church is dedicated to the Prince of Novgorod, Alexander Yaroslavitz Nevsky, who led the famous Ice Battle on the banks of Lake Peipsi on 5th April, 1242 and halted the Germans’ eastward advance.  Before the building of the cathedral, there was a garden on the same site, in front of Toompea Castle, with a memorial to Martin Luther. The well-maintained cathedral is the grandest sacred Orthodox structure in Tallinn. The church’s bell towers hold Tallinn’s most powerful church bell ensemble, consisting of 11 bells, including the largest in Tallinn, weighing 15 tonnes. You can hear the entire bell ensemble playing before church services. The interior, decorated with mosaics and icons, is well worth a visit.
