The Klusfelsen is a sandstone rock in Goslar on the edge of the Harz below the Petersberg.
It protrudes as a rock rib almost 20 meters high and 50 meters long from the almost flat surrounding terrain, which is around 250 meters above sea level.
The sandstone dates back to the Lower Cretaceous, when it was formed in a shallow sea around 110 million years ago.
Since the sequence of layers here runs almost vertically due to block-like uplift in the Early Tertiary, vertical layer surfaces can be seen on the Klusfelsen.
Johann Wolfgang von Goethe visited the Klusfelsen together with Georg Melchior Kraus during his third trip to the Harz on September 2, 1784.
In 1167, a Lady Chapel – the so-called “Klus Chapel” – was set up in a natural cave in the rock room.
It was used as an apartment after the Reformation.
With the romantic movement at the beginning of the 19th century, a chapel was re-established, which fell into disrepair after 1970 at the latest and was even used as a toilet.
In 1983 the chapel was renovated - with outstanding support from the Rotary Club of Goslar.
The rock is protected - no rock samples are allowed to be removed, nor are the rocks allowed to be climbed.
