Haus Eyll, Medieval manor house in Kamp-Lintfort, Germany.

Haus Eyll is a manor house with a rectangular layout bounded by two single-story buildings with half-hipped roofs on the western and eastern sides. The enclosed courtyard in the middle defines the architectural structure of this medieval estate complex.

The estate was built in the 12th century as a fortified castle with water-filled moats to protect the family and surrounding residents from attacks. Over the centuries it lost its defensive purpose and was converted into a residential house.

The castle chapel was probably built around 1430/32 by Tillmann von Eyll in Gothic style. For centuries it served the lords of Eyll, who also maintained the clergy, as a burial place. Around 1796 the parish of Eyll, likely founded in the 17th century, was merged with the parish of Kamp, though the union did not last long.

The farmyard is still worked, so the grounds are not a public park; the preserved boundary wall with its arrow slits now serves as the outer wall of a stable. The round tower stands at the northwest corner of the complex. The moat that once encircled the whole yard was fed by the Eyllsche Kendel.

The outer wall still shows visible arrow slits that testify to its original role as a defensive installation. These details are now embedded in a stable building wall and reveal how the medieval structure was practically adapted over time.
