Ürziger Sonnenuhr, Sundial in Ürzig, Germany

The Ürziger Sonnenuhr is a vertical sundial with a flat dial and a gnomon parallel to the Earth's axis, mounted on the south-facing facade of a former watchtower at river kilometer 119 near Ürzig. It shows true local time, about 32 minutes behind Central European Time. Behind the dial, two rooms of 8–10 square meters are cut into the rock, one above the other; a third level of about 3 square meters retains a window reveal.

The sundial was built before 1893, marking time for the people and wine culture of the Moselle landscape. Its Roman numerals indicate local solar time, which differs from Central European Time by roughly 32 minutes.

The Madonna and Child is a small wooden figure, weather-damaged, standing in a niche at the foot of the rock to the left, not in the dial itself. In the centre of the dial is a niche holding a figure of Kuno I of Pfullingen. Until the wine law changed in 1971, "Ürziger Sonnenuhr" was also a vineyard site name.

The sundial sits directly beside the B53 road as you leave Ürzig and faces precisely south. You can spot it easily from the car or step out for a closer look.

Three rooms were carved into the rock directly behind the dial face, with window frames still visible in the topmost chamber showing how people lived there. This combination of public timekeeper and private dwelling reveals how the cliff face served double duty.
