Charlestown is probably best known for its fantastically preserved Georgian working port.  It is like you have stepped back in time when you walk along the harbour.  There’s no wonder it makes a great film location.  The most recent harbour filming was for the TV series Poldark. There's a lovely walk along the quay and beach too. If you walk out of the town via the South west Coast Path you will reach the remains of Crinnis Cliff Battery. This was built in 1793 to protect Charlestown from the French. Visit: Shipwreck Treasure Museum
