I think to most of the people who ever visited Prague, this is a very well known place :) For everyone else, this is the elevator and stairs in the Old Town Hall Tower (the one with the astronomical clock on it :) ) It’s really great for HDR photos, and nobody minds if you use a tripod in there :)
HDR from three shots, taken with Canon 7D with Sigma 10-20mm lens, from a tripod.
