Hermitage, St Petersburg, Russia. A great deal of the details in my dining in NY came from this hall, which I visited with my team. See the finished room in "Fifth Avenue Style" by Howard Slatkin, out in September from Vendome Press
Westminster Hall - With a history spanning more than 900 years, Westminster Hall is the only part of the ancient Palace of Westminster to survive in almost original form. Built between 1097 and 1099 by William Rufus it has played host to a variety of ceremonies and events. From great feasts and banquets to Tudor disguisings and even an early form of shopping centre!
