s. A variety of different archaeological phenomena have been found at the sites, and all three include the remains of round towers known as
brochs.
Mousa The island of
Mousa has been uninhabited since the 19th century and is best known for the
Broch of Mousa, an
Iron Age round tower which is the tallest still standing in the world and amongst the best-preserved
prehistoric buildings in
Europe. One of over 500 brochs built throughout Scotland, it is thought to have been constructed circa 100 BC. The site is managed by
Historic Scotland. Mousa lies about off the east coast of the Mainland some north of Old Scatness. According to the tentative list application the broch and environs hosts the world's largest colony of
storm petrels and "nowhere else in the world are petrels so accessible to visitors". The site was first unearthed during construction work for airport improvements in the late 1970s. The site is managed by the
Shetland Amenity Trust.
Jarlshof Jarlshof lies close to Old Scatness near the southern tip of the Shetland mainland and has been described as "one of the most remarkable archaeological sites ever excavated in the British Isles". It contains remains dating from 2500 BC up to the 17th century. The
Bronze Age settlers left evidence of several small oval houses with thick stone walls and various artefacts including a decorated bone object. The Iron Age ruins include several different types of structure including a broch and a defensive wall around the site. The Pictish period provides various works of art including a painted pebble and a
symbol stone. The Viking-age ruins make up the largest such site visible anywhere in Britain and include a
longhouse; excavations provided numerous tools and a detailed insight into life in Shetland at this time. The most visible structures on the site are the walls of the Scottish period fortified manor house, which inspired the name "Jarlshof" that first appears in
The Pirate, an 1821 novel by
Walter Scott. The site is in the care of Historic Scotland.
