Burg Veynau, Medieval castle in Euskirchen, Germany.

Burg Veynau is a medieval fortified complex in Euskirchen featuring a central hall building, two corner towers, and two round towers arranged within an inner walled enclosure. The layout demonstrates a typical fortress design with defensive positions at strategic points to protect the inner courtyard.

The fortress was established in 1340 as a stronghold for the Margrave of Jülich in the region. It suffered serious damage during the Thirty Years War but was subsequently restored in parts.

The castle shows the medieval defensive building style that developed along the Rhine region. Walking around the structure reveals how builders of that era integrated protection into every architectural choice.

The castle remains in private ownership, so visitors can observe it from designated outdoor viewing areas that offer the best views of the walls and towers. A visit works best from outside the grounds to see the exterior structure in full.

The castle was not left untouched: French general Lacroix had it burned down in 1708, and the towers received their present domed caps during the rebuilding that followed. A later owner, field marshal Maximilian Carl von Martial, rebuilt the west part of the manor house from 1722.
