50 Банкетов! Написать письмо другу про то как ты провел лето

Dear friend,
Having a great time in Saint-Petersburg . There are many beautiful buildings and architecture. I went to the Hermitage and saw amazing pictures. The Hermitage is situated at the Dvorcovaya square. It is very historical square.
There is a big Peter and Paul Fortress at the center of the city. It was build to protect people from enemies. Also I saw Bronze Horseman. It is monument of Peter the First on the horse.
There is a Saint Isaac's Cathedral near the Bronze Horse.
I have heard much good about theaters so I'm going to visit one tomorrow.
