The largest earth mound in Europe. The largest prehistoric structure in Europe. Nearly five thousand years old, older than the Great Pyramid in Egypt.

Made of chalk, it was white once and encircled by water. The grass came later. A white island, a spiral castle. The moon, with its reflection. A globe in the darkness, an illusion, on a dark solstice night five thousand years ago. Roll up, roll up for your visit to the underworld.
