1814 Frost Fair
During the Little Ice Age of the 17th to early 19th centuries the River Thames completely froze over on eight occasions and London witnessed a series of historic spectacles – The Frost Fairs. In 1814, thousands flocked onto the thick ice to witness and enjoy an impromptu mix of festival, circus, and street show. Tents were erected and makeshift markets quickly emerged as innkeepers and tradespeople eagerly made the most of this temporary frozen wonder. A new bridge replaced the narrow arched Old London Bridge in 1831 and the faster water flow stopped the Thames ever freezing over again. The 1814 Frost Fair was the last of its kind.
