Smolny Convent or Smolny Convent of the Resurrection (Voskresensky), located on Ploschad Rastrelli, on the bank of the River Neva in Saint Petersburg, Russia, consists of a cathedral (sobor) and a complex of buildings surrounding it, originally intended for a convent.This Russian Orthodox convent was built to house Elizabeth, the daughter of Peter the Great. After she was disallowedsuccession to the throne, she opted to become a nun. However her Imperial predecessor, Ivan VI was overthrown during acoup 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 (catholicon or sobor), a blue-and-white building, is considered to be one of the architectural masterpieces of the Italian architect Francesco Bartolomeo Rastrelli, who also redesigned theWinter Palace, and created the Grand Catherine Palace (Yekaterininsky) in Tsarskoye Selo (Pushkin), 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 wasconsecrated 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 theSaint Petersburg State University are located in some of the buildings surrounding the cathedral.

The nearby Smolny Institute is named after the convent.

The name "Smolny" derives from the location, in the early days of St. Petersburg the place at the edge of the city where pitch ("smola" in Russian) was processed for use in shipbuilding and maintenance. As a result the locale was called "smolny" - the place of pitch
