This watergate at the rear of Breda Castle is where the famous peat barge slipped through in 1590 to recapture the city from the Spanish. The twin towers framing the gate make for one of Breda's most photographed spots, especially at night when they are lit up. Freely accessible at any time.
The name means "Spaniards' hole" -- a reference to the Spanish garrison that was duped by the peat barge ruse. Standing at the watergate, you can look through to the castle moat and get a sense of how tight the defences once were. It is one of the rare places in Breda where the medieval topography has survived essentially intact.
