Charles Bridge and Astronomical Clock are salt-free

Charles Bridge in winter The only bridge, where it is banned to use salt in the Czech Republic, is the Charles Bridge in Prague. The National Heritage institute has to solve the every-year problem of historic sights being damaged by salt. That the situation is not made out was proved by the case of Old Town Square Astronomical Clock we informed you last year. Salt fixes wetness, wetness harms the Astronomical Clock.

Prague City Hall now uses sand instead of salt for Old Town Square. Similarly the Charles Bridge, which is undergoing repairs at the moment, and so is more vulnerable to changes in weather, has special treatment – the snow from it is scraped together, thrown from the bridge to Vltava river, and than sand is spread there.
