The Old Town Hall’s Tower is a must visit place in Prague, it’s one of the oldest town halls in the world. The entrance fee to the tower is 250 Kc, and the views are totally worth the visit. The tower is around 70m tall, it was built in the 14th century. The Old Town’s astronomical clock is now the oldest functioning astronomical clock in the world. There are elevators to get to the ticket’s office and to the top of the tower. The views from above are really breathtaking.
