Wasserschloss Bad Rappenau, Renaissance castle in Bad Rappenau, Germany.

Wasserschloss Bad Rappenau is a Renaissance castle standing on an artificial island surrounded by a moat with typical architectural features of the early 1600s. The structure features thick walls, several towers, and a characteristic courtyard that separates the residential area from the outer fortifications.

The castle was built in 1601 by Eberhard von Gemmingen and replaced an older fortress on the same site. The water defense system remained functional for centuries and was an important protection element throughout much of its history.

The castle serves as a venue for art exhibitions where visitors can discover works by various artists. Its rooms are used regularly for cultural events and presentations.

Visitors can explore the castle through guided tours that provide access to the interior spaces and their history. The main entrance is located at Hinter dem Schloss 17, and the site is easily accessible for a half-day visit.

Eight stonemasons' marks are carved into the castle, five of them on the stone spiral staircase of 1601 with its open central newel. Three of those five masons also left their marks at Greckenschloss in Kochendorf, one at the chapel of Schloss Liebenstein, and another mark reappears in 1619 at the town church of Vaihingen.
