Burg Uda, Medieval castle in Grefrath, Germany.

Burg Uda is the ruin of a medieval castle in the Oedt district of Grefrath on the Lower Rhine. Only remnants of the masonry survive; the site lies in the Oedt part of the municipality, not on a fortified hill with towers and bastions.

The fortress was first documented in 1355, marking its establishment during a period of territorial growth in medieval Germany. Over the centuries, the structure was repeatedly rebuilt and modified to adapt to changing military tactics and technology.

The castle grounds are used by visitors for walks, and the stone walls have shaped the appearance of the place for centuries. The setting shows how this fortress once defined life in the region.

The fortress is easily accessible from the outside, with pathways through the courtyard and grounds accessible to visitors. Comfortable shoes are recommended, as some areas of the terrain can be uneven and conditions may vary with weather.
