The Lewes Avalanche 1836
During an exceptionally severe winter, with very heavy snowfall and strong winds, with some snowdrifts reported to be in excess of 10 feet high a crushing avalanche came down off the downs near where the current Cuifail Tunnel is destroying a row of cottages and killing 8 inhabitants.
7 survivors were dug out (the white dress worn by a survivor when she was rescued, Fanny Boakes, is on display in Anne of Cleves House in Lewes).
Some years later a public house called The Snowdrop was built on the site and it is still there.
Why was this the worst avalanche on record in the UK? Because no other avalanche to date has destroyed buildings.
