St. Isaac’s Cathedral

St. Isaac’s Cathedral

St. Isaac’s Cathedral is the largest cathedral in the city. It is also one of the largest one-dome cathedrals of the world after St. Peter Cathedral, in Rome, and St. Paul Cathedral, in London. It was designed by French architect A. Monferan. The construction of the cathedral took 40 years. It is decorated with picturesque mosaics, amazing wall-paintings, and gilded statues. The cathedral is surrounded by 112 monolith granite columns brought here from the suburbs of St. Petersburg. Since the second half of the XIX century St. Isaac's Cathedral was the main cathedral church of the city. Now it is just a museum, but the main religious holidays are celebrated here.
