The castle was probably built by a member of the high nobility to expand their power in this border region.

By the 12th century the noble family had moved to Neu-Schauenburg Castle and were known as the Lords of Schauenburg.

Many of the wooden buildings and fixtures were stripped out of Altenberg and probably moved to Neu-Schauenburg.

By the 20th century the ruins were overgrown and covered by soil with only a few traces of walls still visible.

The excavation discovered over 250 items including a piece of gold and silver jewellery.
