The Lower Castle Antweiler, also known as Unterburg Antweiler, is a moated castle, initially from the 16th century. It is located on the northeastern edge of the Eifel in Mechernich (district Antweiler) in the district Euskirchen. Their counterpart was the Upper Castle Antweiler, which was on the opposite side of the Krebsbach.
The two castles of Antweiler documented the historic ownership of the place from the Middle Ages to modern times. Property in Antweiler had the abbey Deutz and the Bonn pin Dietkirchen. Their governors sat on the lower castle, which they probably founded only in the 13th century, in order to consolidate their rule. In 1345, the lords of Antweiler had obtained from the sovereign, the count of Jülich, the jurisdiction from which developed the subordination Antweiler. Their masters were in the 15th century by Metternich, at the same time inheritors of Deutz and Dietkirchen. In 1488, the lords of Ahr acquired bailiwick and rule, which they divided into two lines at the beginning of the 16th century. The younger line built the upper castle and received the Deutzer Vogtei, which fell back in 1716 to the lower castle. The upper castle was sold to the Jesuit order, 1777 to the Cologne school administration and 1941 to the Raiffeisenbank, which demolished the manor. The only thing reminiscent of the castle is the round tower of the outer bailey with its two-part late Gothic helmet and two heraldic chimneys, one of which is now rebuilt or restored in Konradsheim Castle and the other in the outer building of the lower castle in Antweiler.
Both castles were originally surrounded by water. Since the Krebsbach proved to be an unreliable source of water, the trenches have probably dried up since the 18th century and were leveled in the 19th century at the latest. The lower castle is today owned by baron Raitz von Frentz. The once two-part castle still shows in the walls medieval traces in the shape of key-snaps. The outer wall stands on the defensive wall of the 14th Century, inside 1728 a Halfenhaus has been grown. The main castle is surrounded by a ring wall, which was reinforced with towers and in the west corner of the castle house may have stood. The present house was the gate of the early 16th century, built on a much older corner tower. From another wing, only one approach is obtained.
