The castle is classified as a Swiss heritage site of national significance.

In 1225 the Homberg line died out and the castle was inherited by the Counts of Frohburg.

Over the following years a cadet line of the Frohburg family took the name Neu-Homberg and established a new castle Neu-Homburg near Läufelfingen.

In 1323 the last Count of Neu-Homberg, Werner III, died and the castle was inherited by Countess Maria von Oettingen.

Many of the artifacts, dating from the 11th to 15th centuries, are on display in the Historical Museum of Lenzburg Castle.
