Jarlshof (/ˈjɑːrlzhɒf/ YARLZ-hof)[1] is the best-known prehistoric archaeological site in Shetland, Scotland.

It contains remains dating from 2500 BC up to the 17th century AD.

The remains at Jarlshof represent thousands of years of human occupation and can be seen as a microcosm of Shetland history. Other than the Old House of Sumburgh (see below), the site remained largely hidden until a storm in the late 19th century washed away part of the shore, and revealed evidence of these ancient buildings. Formal archaeological excavation started in 1925, and Bronze Age relics were soon discovered.[13] Jarlshof was one of first two broch sites to be excavated using modern scientific techniques between 1949 and 1952.[9] Although the deposits within the broch had been badly disturbed by earlier attempts, this work revealed a complex sequence of construction from different periods.[14] Buildings on the site include the remains of a Bronze Age smithy, an Iron Age broch, an roundhouses, a complex of Pictish wheelhouses, a Viking longhouse[10][15] and a mediaeval farmhouse. No further excavations have been undertaken since the early 1950s, and no radiocarbon dating has been attempted.
