Very nice entrance. Inside there is something to see, various historical objects. On hot summer days, coolness reigns there, you can sit in the shade of trees, drink water from an outdoor drinking tap.
Tvrjava is the Serbian name for the fortress. That's what they call it in the Niche. Of course, not like Kalemegdan in Belgrade, only the walls are destroyed in places, and the gates. But for those who love history, it will be interesting. One of the main attractions in the city itself.
