Gletschergarten
This tourist attraction, excavated between 1872 and 1875, uses light effects to illuminate stones that have been dramatically pocked and polished by Ice Age glaciers. A private museum on the site, the Alpineum, contains impressive relief maps of Switzerland; there’s an elaborate 19th-century hall of mirrors that seems oddly out of place but is delightfully fun; and a striking modern excavation of the mountain interior tells the tale of millions of years of time. The highlight is the panoramic expansion, affording views across Luzern and Central Switzerland’s mountainscape.
