For the 24th Sept Tag Tuesday 'clock' theme
Prague Astronomical Clock
The clock was first installed in 1410,
making it the third-oldest astronomical clock in the world
and the oldest one still working!
I used photographs which I had taken on two separate visits to prague the background one is in black and white (2002) and the top one colour (2006)
