We've never found one, but we are told that a few of the very old homes in the city still use 120 volt. The national currency is the Czech crown which is usually written as Kc. Hellers are available in 10,20 and 50 coins. For several years you could exchange them at the Central Bank - but no longer.

The other health complaint common to Praguers is the winter hacking cough. This is due to the fact that lots of them smoke and the pollution levels, although better than they once were, are still high.

If this happens the government advises small children to stay indoors. We recommend you do the same.
