A Spiegeltent ( Dutch for "Mirror Tent", from spiegel+tent) is a large travelling tent, constructed in wood and canvas and decorated with mirrors and stained glass, intended as an entertainment venue. Originally built in Belgium during the late 19th and early 20th Centuries, only a handful of these Spiegeltents remain in existence today, and these survivors continue to travel around Europe and beyond, often as a feature attraction at various international arts festivals Two tents used by Teatro ZinZanni have been in (more or less) fixed locations in Seattle and San Francisco for several years. On 1 April 2011, Spiegelworld opened Absinthe at Caesars Palace, Paradise, Nevada in the 26 metre Salon Marlene. In 2007 the first Spiegeltent arrived in Africa and is touring South Africa as part of Madame Zingara's Theatre of Dreams dinner circus extravaganza.
