Wasserschloss Glatt, Renaissance water castle in Sulz am Neckar, Germany.

Wasserschloss Glatt is a water castle in Sulz am Neckar with four corner towers and a gatehouse that surround a restored pond to form a protective perimeter. The structure displays typical Renaissance architectural features with its characteristic layout built around the water.

The castle was founded in the 13th century and belonged to the Neuneck family until 1671, when it passed to the Trier Cathedral chapter. This transfer marked a turning point in its history and connected it with new owners and purposes.

Since 2001 the Kultur- und Museumszentrum has occupied the main building and the former tithe barn, with four collections: a farm museum opened in 1996, a village and lordship museum built on Siegfried Esslinger's collection, a nobility museum with an armoury, and a gallery showing 170 works of the Bernstein School.

The castle operates today as a cultural center with rotating exhibitions throughout the year. Visitors should know that access and opening hours may vary depending on what events are taking place.

The gate tower was placed in front of the Gothic gateway in 1513, and a drawbridge hung here until 1705. Inside the courtyard, the late 13th-century castle survives in a Gothic gate built of humpbacked ashlar blocks. A 1503 rent book records that the farm tenants of Rodt owed 1,800 palisade stakes for the castle's fencing.
