Râșnov

Rasnov Fortress, is located on a rocky hilltop in the Carpathian Mountains, 650 ft. above the town of Rasnov. Strategically located on the commercial route linking the provinces of Transylvania and Walachia, Rasnov differs from other Saxon fortresses in that it was designed as a place of refuge over extended periods of time. As such, it had at least 30 houses, a school, a chapel and other buildings more commonly associated with a village. Recently, the old fortress has been restored to its former glory and today, you can visit the impressive remains. There is also a museum here, hidden behind the ancient walls, where you can find a skeleton buried beneath a glass floor, as well as some other interesting artifacts.
The inner rooms are maze-like, with several wooden ladders linking them and a few so-called secret passages which should keep you busy for quite awhile.
