Saint Isaac's Cathedral was built in St Petersburg. It is dedicated to Saint Isaac of Dalmatia, a patron saint of Peter the Great who had been born on the feast day of that saint. The Cathedral was constructed on the orders of Alexander I between the years of 1818 to 1858 to replace an earlier structure. Under the Soviet government, religious trappings were removed and it became the Museum of Scientific Atheism. With the fall of communism, the museum was removed and regular worship was resumed in the cathedral, although mainly in the left-hand side chapel. The main body of the cathedral is only used for services on feast days.
