Frost fair
A frost fair was a celebration held on the surface of the River Thames when it froze over. Carnival festivities, shows, games, ice skating, shopping and other celebratory events were held on the open surface of the ice.

The Twelfth Doctor later took Bill Potts to the 1814 frost fair, investigating people disappearing on the ice, which turned out to be a giant sea serpent. Lord Sutcliffe planned to blow open the ice during the Fair, enabling the serpent to feed on them all. However the Doctor placed the explosives next to the creature, freeing it from its' chains. When Sutcliffe went onto the ice to investigate, the serpent cracked the ice and Sutcliffe fell through. (TV: Thin Ice)
