Jagdschloss Lopshorn, Hunting castle in Augustdorf, Germany.

Jagdschloss Lopshorn was a two-storey Baroque hunting palace built from 1685 for Count Simon Henry of Lippe, replacing his father's 1657 hunting house. Its entrance was framed by four Neoclassical columns, flanked by two reclining deer, with three sandstone figures of a hunter with dog and two wolves between the columns. A small tower carried a clock in the front gable and a weathervane shaped as a leaping horse; the interior was later redone in Neo-Renaissance style. Flanking it stood the stables and the armoury, plus a dairy, all within a symmetrical layout and a plain fence with a central gate.

Count Hermann Adolf zur Lippe built a hunting house here in 1657; his son Simon Heinrich replaced it in 1685 with a castle that kept its basic form until 1945. The site was destroyed by arson on 11 June 1945, not 1951, and the ruins decayed, leaving little visible today. Plans exist to rebuild the castle and stud at the original spot.

The Senner horse, one of Germany's oldest known breeds, was first documented in the Senne heath in 1160; in 1493 a count recorded 64 animals, including 23 mares and 18 foals. In 1684 Count Simon Henry moved the stud buildings next to the new hunting lodge, and the horses shaped the open heath by grazing. Stallmaster Prizelius described the mares living like wild horses, fed at the Lopshorn stables only when deep snow covered the heather.

The site lies within an active military training area and is closed to the public. Entering the area is strongly discouraged, as military activity continues there on a regular basis.

The fire of 11 June 1945 was arson, and the ruins were left to decay, so almost nothing of the complex remains today. What survives are Baroque coat-of-arms stones from the Zeughaus, bearing the arms of Count Friedrich Adolf, his wife and the wife of Count Simon Heinrich. Plans exist to rebuild the castle and stud at the old site from the original plans.
