A crannog is a type of ancient loch-dwelling found throughout Scotland and Ireland dating from 2,500 years ago. Many crannogs were built out in the water as defensive homesteads and represented symbols of power and wealth.

The earliest loch-dwelling in Scotland is some 5,000 years old but people built, modified, and re-used crannogs in Scotland up until the 17th century. Perthshire crannogs were originally timber-built roundhouses supported on piles or stilts driven into the lochbed although in more barren environments and in later periods tons of rock were piled onto the lochbed to make an island on which to build a stone house. Today crannogs appear as tree-covered islands or remain hidden as submerged stony mounds. Several hundred have been discovered so far in Scotland although only a few have been investigated.

This authentic recreation at The Scottish Crannog Centre is based on the excavation evidence from the 2,500 year old site of 'Oakbank Crannog', one of the 18 crannogs preserved in Loch Tay.
