Folly Pier is a disused stone shipping quay, located on the Isle of Portland, Dorset, England; part of the Jurassic Coast.
[4] The limestone quarries of East and Penn's Weares were the location of Sir Christopher Wren's first workings for stone to rebuild London after the Great Fire of 1666.
[5] The stone was shipped from the adjacent Durdle, Folly, and King's Piers.
[6] Once quarrying in the area was reduced, and quarries moved inland from the cliffs, the pier fell out of use, and any cranes were removed.
The surrounding area was chosen for the site of Folly Pier Waterworks, which was built in 1855 by John Coode for the government.
