Burg Gleuel, Medieval castle in Gleuel, Germany.

Burg Gleuel is a two-winged, two-storey water castle of whitewashed brick surrounded by moats fed by the Gleueler Bach. The six-axis main wing faces the street with a curved crow-stepped gable, reached by a bridge flanked by two marble lions; a taller four-axis hipped side wing joins it via a stair tower. Outbuildings enclose a horseshoe-shaped courtyard.

Burg Gleuel was first documented on 4 June 898, when King Zwentibold of Lotharingia gave a Salhof at Gleuel (Gloulo) with twelve other hides and the church to Essen Abbey. In the mid-13th century castle and village passed to the Cologne cathedral chapter. Johann von Cölln of a Cologne councillor family acquired it in 1630 and in 1632 rebuilt the original four-wing complex as the present two-winged one, as a gable stone records. In 1726 it returned to the cathedral chapter by hereditary purchase, and secularisation brought it into private hands in 1802.

The name Gleuel appears as Gloulo in a charter of 898. The Rittersaal inside the main building has a Cologne ceiling bearing the coats of arms of the von Cölln and von Mülheim families, dated 1685. The hall is used occasionally for concerts of the Erftkreiszyklus series, held in turn in the manor houses of the district.

The castle stands in a park in Gleuel, surrounded by the water ditches of the Gleueler Bach; the park is open to the public, but the castle itself is normally closed because the owner lives and works there. It opens for the Erftkreiszyklus concert series of the Hürther Musikseminar and other cultural events. The entrance is reached over a bridge flanked by two marble lions.

The gateway bridge is flanked by two marble lions, and a stone in the gable bears the year 1632, when Johann von Cölln rebuilt the four-winged complex as the present two-winged one. The owner today lives on site and keeps a small classic-car museum in the outbuildings.
