Saint Isaac's Cathedral or Isaakievskiy Sobor (Russian: Исаа́киевский Собо́р) is a cathedral that currently functions as a museum in Saint Petersburg, Russia. It is dedicated to Saint Isaac of Dalmatia, a patron saint of Peter the Great, who had been born on the feast dayof that saint. It was originally built as a cathedral but was turned into a museum by the Soviet government in 1931 and has remained a museum ever since. In 2017, the Governor of Saint Petersburg offered to transfer the cathedral back to the Russian Orthodox Church, but the church has not exercised this offer.
