Like other towns also Prague, the capitol of Czech Republic has few nicknames. The most famous one is “The city of a hundred spires” or “The city of one hundred spires” (Stovezata Praha in Czech language).
So, is it true? Does Prague really has 100 spires? The Czech writer Josef Hormayer is the author of this nickname. In the 19th century the Czech mathematician Bernard Bolzano counted up to 103, but a more recent count from the top of a helicopter has counted more than a thousand. At any rate one of the most fitting nicknames to this day.
So go take a tour and while you at it, count all the spires!
