De Parade.

De Parade is on for two months around different cities in The Netherlands. Theatre, music, food, drinks, games and shops. The entry is free from 15:00 to 17:00. Yesterday was the last day here in Rotterdam but it will be going to Den Haag, Utrecht and Amsterdam next. (Speaking a little Dutch is a bit of a must to enjoy the plays, of course.)
