Burgholz is a hill in the Gilserberg Heights near the town of Kirchhain in Marburg-Biedenkopf, which is 379 metres (1,243 ft) high.

Since 1968, the top of the Burgholz has had the Hunburgturm, a 28.5 m high wooden observation tower, which provides a view of peaks in the Rothaar Mountains, including Kahlem Asten, Ziegenhelle, Bollerberg, and Sackpfeife.

Peaks in the Gladenbach Uplands are also visible, including Dünsberg, Rimberg, Knüll, Kellerwald, and the Vogelsberg range.

[2] On the northwest spur of Burgholz, 6 km north of Kirchhain, are the ruins of Hunburg Castle, from roughly the 8th century.

The ruins consist of fortifications with sections of trench and walls, a pincer gate in the southeast, and what is potentially a basement from a now-absent building.
