Portavadie (Scottish Gaelic: Port a' Mhadaidh) is a village on the shores of Loch Fyne on the west coast of the Cowal peninsula in Argyll and Bute, Scottish Highlands. The Portavadie complex was built by the then Scottish Office for the purpose of constructing concrete platforms for extraction of oil from the North Sea. However, the intention was soon overtaken by acceptance that steel platforms were the future for the oil industry in Scotland. Despite suggestions to turn the complex into a holiday village, it lay redundant until in the mid-1980s the enclosed port was used by a local fish farm company.
