SPIEGELLTENT

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.
This tent, called the 'Victorian' is sited outside the Royal Bath House in Harrogate for a couple of weeks for their Summer Festival so if your anywhere near its worth a visit.
