Burg Adenbach, Medieval castle in Ahrweiler, Germany.

Burg Adenbach is a castle at Adenbachhutstraße 1 in Ahrweiler. The long, two-storey rubble-stone building, partly half-timbered, has an octagonal tower and stepped gables on the eaves side and the western narrow side. It was largely remodelled in 1903 and converted into a hotel with restaurant after renovations in the late 1980s.

Burg Adenbach traces back to a late medieval manor house. In the 19th century it passed into the ownership of Freiherr von Loë. During the 1930s the building housed a youth hostel, and after extensive renovation at the end of the 1980s it became a hotel with a restaurant.
