The original size of the core castle is unknown, but it must have been at least three times the size of the area preserved today. The core castle was surrounded by a two-metre-wide circular wall. In front of it was a 14-metre-wide moat dug into the rock. The buildings connected to the curtain wall on the inside are farm buildings and towers that were rebuilt several times and were only erected in the second half of the 12th century.
The excavated walls were fortified, partially completed and left in the same condition, even if walls appear next to each other that did not originally exist at the same time.
Incidentally, the neighbouring quarry is one of the Sauerland-Seelenorte. It is definitely worth visiting the limestone quarry, which is overgrown with grasses and ivy and surrounded by beech trees(www.lennestadt-kirchhundem.de/de/neusta-touren/seelenortwanderung-steinbruch-peperburg).
If you prefer to travel on two wheels, you will pass below the Peperburg on your tour of the SauerlandRadring.
