Burg Neuhewen, Medieval castle in Engen, Germany.

Burg Neuhewen is a medieval stone fortress in Engen that stands on elevated ground and adapts to the natural topography of the surrounding area. The defensive walls and towers follow the contours of the terrain and use these features for their protective layout.

Burg Neuhewen was built in the mid-13th century by the Lords of Engen (Hewen) and passed to the Habsburgs at the end of that century. In the 14th century it was held in pledge by the Counts of Hohenberg, and from 1375 to the early 16th century it belonged to the Lords of Reischach. Bavarian troops destroyed it in 1639 during the Thirty Years' War; the Fürstenbergs acquired the ruin in 1661, the Ebinger family bought it in 1671, and it returned to Fürstenberg ownership in 1751.

Locals call the ruin Stettener Schlössle, after the village of Stetten below it. The castle was built in the mid-13th century by the Lords of Engen, also called Hewen, and passed to the Habsburgs by the end of that century. From 1375 to the early 16th century it belonged to the Lords of Reischach.

The ruin is not developed for tourism: there is no signposted path to the site and no marked parking area, so the approach on the Neuhewen must be found independently. Since about 2005 the grounds and the eleven-metre bergfried have been closed off with barriers and NATO wire; entry is not possible.

The castle is the highest-lying fortress in the Hegau, yet it has no signposted path or marked parking, and since around 2005 it has been closed off with barriers and NATO wire. Until then, visitors could enter the grounds and climb the tower.
