I was inside, it looks beautiful, but everything historical has already disappeared (redone for the needs of the military headquarters). The architecture is impressive, constantly maintained in a well-maintained condition.
I do not recommend visiting, it may take a year or even more)))
Tyshkevich's Palace in Volozhin k is a complex of palaces, a church, and a winter garden of nobles. It is very beautiful and majestic, in addition, there used to be a park area, but now it has significantly decreased. There is an eco-trail near Volozhin, where you can see tarpans and a lake with a huge number of swans and ducks. This is my corner, I love it very much
