Considering the Anita Siweris in Cochem?

The castle tour 14: the well by ATLC
The castle well yields water from 50 metres deep. It is rainwater that comes through the rock to the Mosel. If it were to be ground water, the well would have to be dug 50 metres deeper!
Address: Schlossstr 36, 56812 Cochem
Directions: Take a shuttle bus from the parking lot near the train station or do the steep climb (about 15 minutes) on foot. If by car: drive west along the Mosel, then turn right into Schlossstrasse. But beware: only about 20 places for parking!
