Prague, Czech Republic
Our day started up at Castle Town and we walked through security into the Royal Palace, watched the changing of the guard then entered St Vitus Cathedral (only took 1000 years to finish it!). This also has great views of the city and Vltava river.
Next we walked across the Czech bridge to the Jewish quarter and down to Old Town square, just in time to watch the astronomical clock chime 11 (apostle comes out and statue switches sceptre from one hand to the other)...
