Mathildenhöhe, Darmstadt

The Mathildenhöhe in Darmstadt is undoubtedly among the most stunning architectural specimens of the Art Nouveau period—it’s an ensemble of a wedding tower, a Russian chapel, a lily basin, and an art exhibition building. Its eye-catching colors, gleaming golden domes and the fact that it’s the tallest structure in the city ensure that it is spotted from miles away. The building offers guided tours, including ones designed especially for children. As a part of the tour, you can also visit the ancient reservoirs that are still filled with water.
