Burg, Medieval fortress in Lauterbach, Germany.

Burg is a fortified structure in Lauterbach with thick stone walls, Gothic lower levels, and a Renaissance entrance portal. The complex encloses a courtyard containing a fountain and displays elaborately carved coat of arms stones in its masonry.

The structure was first documented in 1266 when Lauterbach was elevated to town status and required fortification. It served across generations as both an administrative headquarters and residence for the ruling family.

The castle is also called Lauterbacher Schloss, a name that recalls its conversion from a Gothic fortress into a Renaissance palace. Its courtyard keeps the layout of the second half of the 17th century, and the gate carries a coat-of-arms stone with the number 100.

The complex now houses the administration and archive of the Freiherren Riedesel zu Eisenbach, so the buildings are working offices rather than a museum. The castle gate carries a stone bearing the number 100 (a "Cent") and the same figure in its coat of arms. The courtyard layout from the second half of the 17th century survives, so visitors move through a space shaped in that period.

The castle gate carries a stone bearing the number 100 and the same figure in the Riedesel coat of arms, a detail easy to miss when passing through. Volpert Christian Riedesel zu Eisenbach, born here in 1710, became a Saxon infantry general and governor of Dresden.
