Abkhazia never ceases to amaze! Gagra is the most beautiful of the 7 cities of the Republic. Silina's cottage is one of the most beautiful abandoned buildings. The Moorish style is fascinating..
I highly recommend visiting Stalin's dacha (there's a brain explosion there)
A very beautiful abandoned building, the building was built in the Art Nouveau style. The current state, I must say, is quite decent. Admission is free! The inside of the stairs is in pretty decent condition.
A very interesting building, a curious layout, inside is 'construction clean'. There is a prayer tower on the roof. An interesting balcony of 1 sq.m on the 3rd floor. Alas, the abandonment.
