On the outer side of the curve, the Tolvajos brook eroded the rock wall. After a while, the volcanic rock with a less resistant structure no longer supported its own weight and fell into the brook.

In this place, the stream flowed under the fallen rock, which resembles a small cottage, a "hut".

According to tradition, the place was named "The Hut Stone".

It is accessible from the national road 13A to the Chirui Baths.
