St. Peter and St. Paul's Cathedral is the cathedral church of the Roman Catholic Apostolic Administration of Estonia. Catholicism was introduced to Estonia by force via the Northern crusades and dominated religious life during the Middle Ages. However, following the Reformation during the 16th century, Lutheranism took its place as the dominant faith, and during the time of Swedish rule in Estonia, Catholicism was banned.
Following Sweden's loss of Estonia to the Russian Empire during the Great Northern War, religious freedom was introduced by the new authorities. In 1799, the Catholic parish had grown large enough to be granted the former refectory of the long-since closed St. Catherine's Monastery as a place of worship on the site of the present church. In 1841, designs were made for a proper new church building for the site, which had grown too small. The architect was the well-known St. Petersburg architect Carlo Rossi. He designed a neo-Gothic basilica, without an apse, with a neo-classical exterior.
Between 1920 and 1924, the main, western façade received its present look, a work by architects Erich Jacoby and Franz de Vries somewhat deviating from Rossi's original façade. The interior of the church still reflects Rossi's design, however the wooden, neo-Gothic decoration has been removed. The cathedral has undergone a series of renovations, the latest in 2002–2003.
The cathedral incorporates several works of art, including works by local Baltic German artists Carl Sigismund Walther, Robert Salemann and a copy of a painting by Guido Reni.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
