Hammerkopfturm Erin Mine Shaft 3

The Hammerkopf Tower in Castrop-Rauxel is an important witness to the mining past. Built above shaft 3 of the Erin colliery in 1920, it is the oldest of its kind in North Rhine-Westphalia and is surrounded by a special mysticism. A Celtic tree circle in memory of Mulvany has been created around it. An interesting sight and a landmark that can be seen from afar.

Erin's Hammerkopf Tower was one of only ten towers built in the Ruhr area in the 1920s. From 1937 until the mine was closed in 1983, shaft 3 was only used for cable travel; The coal left the mine through shaft 7 on the edge of Castrop-Rauxel city center.
The Hammerkopf Tower was restored in 1993 with state funds. The town of Castrop-Rauxel created a “Celtic tree circle” around it, paying tribute to the founder of the mine. For his Celtic ancestors, the circle of trees served as a calendar and each individual tree in it represented a certain characteristic that could be transferred to humans.
