Its seven storeys used to house a 200,000 litre (44,000 gallon) tank which supplied this part of Vinohrady and Vršovice with water pumped from the Vltava and from the Kárané water station. The tower formed part of a vast network which expanded rapidly from about 1912 onwards. Although it's no longer open to the public, from its observation deck one can apparently admire the view as far north as the Krkonoše Mountains, near the border with Poland.
The handsome clock is operated by a mechanism designed by Ludwig Hainz of Prague, and the tower itself is embellished with the crest of Vinohrady, and sculptures of herald angels, all, like this one, blowing their own trumpets.
It is a great shame that there is not more readily available material about Turek: he seems to me to have been a superb architect who deserves a stronger reputation in his own country, let alone abroad.
