Not all lighthouses are on "dry" land, or even on an island as we know it.

For some lighthouses - there is much less room and land for the lighthouse keepers to stretch their legs.

One such lighthouse is Longships Lighthouse off the coast of Land's End in Cornwall, United Kingdom.

This video shows very well the remoteness of Longships lighthouse - and its helicopter landing pad on the top of the lighthouse - typically used on such lighthouses to be able to deliver supplies and people.
