Bayanne House at Sellafirth, Yell was once the centre of a small estate, created in the late 18th century by the Hoseason family. It now forms Bayanne House Museum, run by Liz and Tony Gott, a visitor centre where, amongst others things, folk can watch the making of three-dimensional interpretations of the environment being created in Shetland wool, or explore the croft. Sellafirth is rich in wildlife, Basta Voe being a particularly famous spot for otters.
They have also created a marvellous genealogy website, Bayanne.info, which has revolutionized the process of 'reddin kin' (dialect: establishing who is related to who, and in what way).
There are also the remains of an Iron Age roundhouse as well as a Bronze Age construction, which were excavated between 1995 and 1997 by EASE Archaeology on behalf of Shetland Amenity Trust and Scottish Heritage.
