are small stone sheds with a roof of a large flat stone
covered with earth and turf. The walls are built of
stones with little gaps between them. This means that
the wind can whistle through and help things kept inside
them dry and cool. In a windy place like St Kilda it's
a perfect design!
They were used by the St Kildan people to store dead
seabirds (for eating), eggs and feathers, crops and
peat and turf (which were used as fuel). There are 1,260
of them all over the main island of Hirta.
Today cleits make ideal homes for
many birds, including Storm and Leachs petrels, which
have a very unusual call.
