The precise statistics of the Prague information service says that the Old Town Hall and especially its 59 m tall gothic tower are one of the most visited Prague monuments. In the past, an outbuilding for the astronomical clock, which has been pride of the medieval technology, was placed between two its southern reinforcing piers. In the tower’s floor there was established a town-hall chapel, which was later on extended to the east with an outbuilding on a vaulted arcade, closed with an altar bay. It is favourable that the observation gallery of the Old Town Hall has been adapted for wheelchairs. It was caused by reconstruction of the tower interior which ended at the end of 1999. In the first phase the lifts inside the town hall building were replaced. In the following phase a neo-formation, a subtle metal structure of a glass lift, was installed. Difference of several steps between the two lifts has been balanced by a mobile platform for disabled people. The new lift goes through the former empty space; traditional frame has been formed by stone walls and reinforced-concrete ramp. Passenger gear panoramic elevator has the following technical parameters: loading capacity 750 kg or 10 people, speed 1 m/s, lift 24,30 m. Authors of the design are: academic arch. Marek Houska, chief designer – ing. Jiří Grosz, steel structures – ing. Michael Trnka. The new elevator ceremoniously started its operation on 1st December 1999. Thus everybody may enjoy the wonderful view from the gallery of the Old Town Hall tower. And at the same time everybody may see for his/her eyes that the adjective of hundred-spired Prague is more than true. The view is especially imposing in the evening when the single buildings are illuminated. Among the numerous views, eastern part of the Old Town Square, which consists of the Church of the Virgin Mary before Týn, the Bell House and the Kinský Palace, is very interesting.
