Gut Schlagbaum, Former water castle in Holweide, Cologne, Germany

Gut Schlagbaum is a former water castle at Schlagbaumsweg 1 in Holweide, Cologne. Only part of the outer bailey survives, with a 16th-century corner tower and gatehouse; above the gate is a Renaissance relief of Adam and Eve framed by cartouches and fruit garlands. The manor house burned down and was not rebuilt after 1950. The private grounds now serve as homes and studios for freelance artists.

Gut Schlagbaum was recorded before 1600 as "Schiederichs Güter"; in 1381 a "Johann van Lach" appears among the sworn men of Hof Herl. In 1615 Hermann Suderman was enfeoffed with the estate by the Hofgericht Rolshoven, and his line died out in 1639. In 1741 Anna Margaretha Constantia von Deutz sold it for 2,000 Taler to her cousin Johannes Christoph Joseph Rensing. The name Schlagbaum comes from a toll post at the border with the Electorate of Cologne's Amt Deutz.

The name Schlagbaum refers to a former toll barrier at the border with the Electorate of Cologne's Deutz district. Above the gate of the 16th-century outer bailey is a Renaissance relief of Adam and Eve framed by cartouches and fruit garlands, possibly echoing nearby field names containing "Paradies".

The grounds are privately owned and access is restricted, so it is best to check beforehand which areas are open to visitors. The best view of the structure can be had from the stream bank, where footpaths run along the property edge.

The estate was never a working farm of consequence: in 1764 it measured just 58 Morgen (about 15 hectares). It was already leased out in the 17th century, so its owners did not live there themselves. The gate relief of Adam and Eve may borrow from nearby field names containing "Paradies".
