bergfried reveals at a certain height the handle and rear part of a trowel. This tool was probably embedded there by workmen in memory of a colleague who fell and was killed during restoration work. This trowel is supposed to have been worked into the wall at the exact height from which the man fell (the exact date must be before 1970, but cannot be more precisely estimated).
