In 1986, a police car crashed into a street after a burst water pipe had washed out the road. This led to the rediscovery of the cellar labyrinth, which presumably stretches over 40 km. The city faced a problem because the city's structural stability was at risk. The investigation revealed that the passageways and cellars had been completely filled—partly with waste—or were still owned by private individuals. However, it was decided to preserve a 500 m labyrinth and open it to the public. Since no historical records exist regarding the cellar labyrinth, nothing is known about its use. Presumably, other goods were stored in the cellars besides wine. Small niches in the walls indicate that these were markers for the ownership of the warehouses. The cellar labyrinth consists of seven levels that were dug horizontally into the mountain and connected to each other. The cellar vaults belonged to the first person to excavate the space, regardless of which house it was located under.

A beautiful view. But there's a lot of renovation work to be done, I'd say.

Unfortunately, the Swiss house looks run-down. The roof terrace is locked, but there's also a great view from below the house.

The drift shows marine deposits from the Oligocene period (30 million years ago). Mussels and snails are the most common fossils, but fish remains such as shark teeth and small creatures and micro plants can also be seen. The caves at the base were created during World War II. They served as a place of refuge from air raids. The area is protected by a fence.
