The City of Prague is crowned with many complimentary names. One of the most frequently used names is ‘The City of a Hundred Spires’ on Vltava River. Indeed, if we look around from one of the look-out spots we can literally see a forest of towers and spires. These towers and spires embellish the numerous religious buildings as well as draw our attention to some remarkable communal buildings. The historical water-towers are also very significant in Prague’s panorama. In the past they were essential for life in the city the same way as were the detached belfries. Corner towers mostly add grandeur to some of the palaces and common houses, especially in Old Town and New Town, Lesser Town and in Hradčany. Even our era has contributed to the over-all list with many buildings of industrial architecture. We can therefore state that the name ‘The City of a Hundred Spires’ is more than an historical matter. In reality Prague prides itself with several thousands of towers and spires. Consequently our virtual tour and its follow-up text can only possibly include a small fragment of information about Prague’s towers and spires. We believe however, that we are showing the most popular and interesting towers many of which are open to the public.
