The museum has at its heart a collection of items from and about South Uist collected by a local Parish Priest, Father John Morrison, during the 1950s and 1960s. It also sets out the background to an island that is incredibly rich in archaeological remains dating from the bronze age to the Viking era. Some of the exhibits are set out thematically: tools from a blacksmith's shop for example. Others are contained within the rooms of a recreated croft house.
