Although the Isles of Scilly is the largest archipelago in the UK, only five of the islands are now inhabited, leaving about 140 uninhabited. Some of these uninhabited islands, that offer a haven for wildlife, especially seabirds, are often frequented by day boats, whilst others are purposely left completely alone.
On Tean and St Helen’s you can still see the ruins of early Christian chapels. Or on Samson, just across the water from Tregarthen’s, you can see evidence that it was once inhabited by farmers and fishermen, who left in the mid-1800s, with the ruins of granite homes, barns and boatsheds still visible.
Shipwrecks also feature in the history of Scilly and the islands. For example The Western Rocks are a memorial to the many sailors lost on Bishop Rock, which is a 50m high column of rock, covered completely at spring high tides. On top of it now is the well known Bishop Rock lighthouse, the most south-westerly lighthouse in the UK.
Boat trips are available to see much of the rugged and wild islands, the amazing bird life, the many seals and maybe even a dolphin or two.
