Crannogs are a type of ancient loch-dwelling found throughout Scotland and Ireland.
Most seem to have been built as individual homes to accommodate extended families. Similar settlements are found throughout the rest of Europe.
The crannog reconstruction which forms the focal point of the Scottish Crannog Centre was built by The Scottish Trust for Underwater Archaeology. It was created to promote the research, recording, preservation and interpretation of Scotland's underwater heritage.
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 AD. Here in Highland Perthshire the prehistoric crannogs were originally timber-built roundhouses supported on piles or stilts driven into the loch bed.
In more barren environments, tons of rock were piled onto the loch bed to make an island on which to build a stone house. Today the 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.
