St. Peter and Paul's Cathedral
St. Peter and Paul's Cathedral was designed by Carlo Rossi and completed in 1841. It is the Catholic Cathedral of Tallinn. During the period of Swedish rule (1561-1721) Catholicism was banned. When Sweden ceded Estonia to the Russian Empire at the end of the Great Northern War, the new authorities introduced religious freedom. In 1799, the Catholic parish grew and took over the use of the former refectory of St. Catherine's Monastery, which had remained closed since the ban. The refectory was used as a place of worship and is located on the site of the present church. In 1841, as the place of worship had become too small, a new church was designed by Carlo Rossi.
