House without a Roof (Kallmünz)

Highlight • Cave

The "House Without a Roof," as it is officially known, is a still-used cave dwelling in the Upper Palatinate market town of Kallmünz. The cave is located north of the Vils River at the southern end of the Schlossberg (Castle Hill), upon which the Kallmünz Castle ruins stand. The entrance is set back from Vilsgasse (Vils Lane) at the foot of an approximately 20-meter-high limestone cliff of the Schlossberg, and access is via a passage between the listed residential buildings at Vilsgasse 26 and Vilsgasse 28.

The house consists of a natural cave in the dolomite rock, the opening of which is closed off by a plastered wall with a door and windows. Inside, there is a hallway, a living room, two storage rooms fitted into rock niches, and a historic smokehouse.

The oldest known mention of the cave dwelling is found in a document dated 1707, preserved in the land registry archive in Amberg. In the 19th century, it was also referred to as the "House Under the Rock." In 1908, it was sold to the owner of the blacksmith's shop located across the road, and it remains in his family's possession. The last permanent resident left the house in 1937 because he developed rheumatism due to the damp cave air.

Kallmünz Stone Bridge

Highlight • Bridge

Here is a double atonement cross incorporated in railing, which was carved from a single stone and connected to the crossbar. These tell the following story:

A pair of scissors and a cross tell the story of an atonement and a deadly dispute. Here a tailor should have stabbed a baker or vice versa. In a modification of the above legend, a tailor and a baker, both from Kallmünz, are said to have fought a duel on the Naabbrücke, which ended fatally for both.

Confluence of Naab and Vils

Highlight • River

Nice place to linger, the confluence of the Naab and Vils. Here you have a beautiful view of the Kallmünzer Castle and the town. You can either drive to the confluence via Gessendorfer Straße, or via the little-traveled road to Krachenhausen.
