Haus Gripswald, Moated manor house in Meerbusch, North Rhine-Westphalia, Germany

Haus Gripswald is a four-winged brick farm complex near Ossum in Meerbusch, with a two-story rectangular main house dating from 1547. It has a round tower annex and a stair tower annex, plus a three-winged economic building. The round tower was raised by one story in the early 19th century.

The estate was first mentioned as a farmstead in the 12th century and gained fiefdom status in 1422. It remained under electoral control until secularization changed its legal standing.

The round tower holds 28 Romanesque double columns salvaged from the ruins of St. Maria and Andreas monastery near Dormagen. These columns show how the castle connected to religious buildings across the region.

The eastern wing is now privately occupied and can only be viewed from outside. Visitors should respect the property boundary and observe the structure from publicly accessible areas.

The upper storey added to the round tower in the early 19th century carries 28 Romanesque double columns taken from the ruins of the Premonstratensian monastery of St. Maria and Andreas in Knechtsteden, destroyed in the 18th century. The columns are set into the facade as decoration.
