I have been once to Saint Petersburg. It is the most beautiful city I have ever seen! It is located on the Neva River at the head of the Gulf of Finland on the Baltic Sea. There are very many sightseeings in Saint Peretsburg. I have seen Saint Isaac's Cathedral, Saints Peter and Paul Cathedral, Admiralty building, Kazan Cathedral, Catherine Palace, Palace Square. I have visited The Russian Museum, Museum of Water. I really enjoyed my visit
