A very broken relief of the capital city already made a necessity of a building of many stairways the centuries ago. They were built on the places where steeply rising slope didn´t allow a construction of a classical street. One of the oldest stairways are the New Castle Steps. They starts in Thunovská street and empty into Hradčany Square on the edge of the Castle ramp. They have 209 stairs. Very famous are the Old Castle Steps leading from Klárov to an easter gate under the Black Tower. They have 101 stairs. The longest steps in Prague are the steps leading from Vlašská street in Malá Strana upwards to Petřín hill. They have 306 stairs.
