Smolny Convent (Voskresensky) is a Russian Orthodox convent built to house Elizabeth, the daughter of Peter the Great. After she was disallowed succession to the throne, she opted to become a nun. However her Imperial predecessor, Ivan VI was overthrown during a coup d'état (carried out by the royal guards in 1741). Elizabeth then decided against entering monastic life and accepted the offer of the Russian throne and work on the convent continued with her royal patronage.
The convent's main church, a blue-and-white building, is considered to be one of the architectural masterpieces of the Italian architect Francesco Bartolomeo Rastrelli, who also redesigned the Winter Palace, and created the Grand Catherine Palace (Yekaterininsky) in Tsarskoye Selo, the Grand Palace in Peterhof and many other major St. Petersburg landmarks. The Cathedral is the centerpiece of the convent, built by Rastrelli between 1748 and 1764. The projected bell-tower was to become the tallest building in St. Petersburg and, at the time, all of Russia. Elizabeth's death in 1762 prevented Rastrelli from completing this grand design.
When Catherine II assumed the throne, it was found that the new Empress strongly disapproved of the baroque style, and funding that had supported the construction of the convent rapidly ran out. Rastrelli was unable to build the huge bell-tower he had planned and unable to finish the interior of the cathedral. The building was only finished in 1835 by Vasily Stasov with the addition of a neo-classical interior to suit the changed architectural tastes at the time. The Cathedral was consecrated on 22 July 1835; its main altar was dedicated to the Resurrection and the two side altars were dedicated to St. Mary Magdalene and Righteous Elizabeth. The church was closed by the Soviet authorities in 1923. It was looted and allowed to decay until 1982, when it became a Concert Hall.
Today, Smolny Cathedral is used primarily as a concert hall and the surrounding convent buildings house various offices and government institutions. In addition, the faculties of sociology, political science and international relations of the Saint Petersburg State University are located in some of the buildings surrounding the cathedral.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
