The Temple of Mercury is carved into a rock; you can only see the portal from the front; if you walk around the rock, you get the impression it's just a rock. Fascinating.

On this hiking highlight, we encounter the remains of a temple dedicated to MERCURY (Latin: MERCURIUS). Dating back to pre-Christian times, the deities of Roman and Greek mythology in particular have been preserved in the collective memory of people in Europe to this day. MERCURY is the "messenger of the gods" in Roman mythology; his counterpart in Greek mythology is Hermes. Both have the interesting combination of being gods of trade and merchants, but also of thieves.

On the site of the ruins of Wasenburg Castle, there are the remains of a much older building: a Roman sanctuary dedicated to Mercury. Parts of the temple were rebuilt in the 19th century.

Lake Reichshoffen is an essential natural space located about 2 km from the town center of Reichshoffen and near the village of Nehwiller, and serves as a refuge for a multitude of animal species. Located on the water, an ornithological observatory has been installed there by the Northern Vosges Regional Nature Park, which can be used by animal and plant lovers all year round, day and night: since 1982, 130 species have been recorded on the water or in the surrounding wetlands, of which about 40 are nesting species that breed there.
