The reason why one should see the city is the monastery. The monastery of Sergiev Posad is one of the most beautiful monasteries in Russia and one of the principal spiritual centers of the Russian Church. It is a combination of a fortress and a monastery. The seminary of the Russian Orthodox Church is located in the buildings of the complex. There are several churches to see, a holy source and in general the whole complex with its massive walls and gates is very picturesque. There are no admission price to pay except for the museum, which shows old religious objects and woven pictures of saints. At the weekend the monastery can get very crowded, as it hosts some very important icons at least copies of them. In return it can be very interesting to observe the believers kissing the icons and praying for hours.
The grave of Boris Godunov of Pushkin's play and Russian history and some family members is also located here.
