Each June since 2010, the waterways in the Dutch city  of ‘s-Hertogenbosch —aka Den Bosch—have been the venue for one of the Netherland’s most surreal and wonderful events. Inspired by the macabre work of local painter Hieronymus Bosch, local creatives from various disciplines—music, art, dance, theater, architecture—along with hundreds of volunteers build delightfully weird floats that are paraded through the city.

Beginning tonight, and again on Saturday and Sunday, the water-borne parade with thrill the crowds of spectators lining the River Dommel. Since Den Bosch is celebrating the 500th anniversary of Hieronymus Bosch’s death all this year, the parade is expected to be a lollapalooza. Here are some photos and a video from last year’s parade. The Bosch Parade website should have images and videos up by Sunday.
