Online jigsaw puzzles of Czech Republic

In 2003 we stayed a week in the Czech Republic and also visited the capital Prague of which we have made a special puzzlepage.
By default the puzzle has 99 pieces on a large screen down to 12 on a mobile device. But you can change this on the right side by choosing another number (from 6 to 1200 pieces). Puzzles with a red edge are new!
