This square enclosure on the island of Noss was built by the Marquis of Londonderry in 1870 for the breeding of Shetland ponies. They were required for use in his coal mines in County Durham.
This 18th century merchant's booth, with its own pier, has displays on the Hanseatic trade and the history of Whalsay. From this harbour Shetland merchants once exported dried fish to Bergen and various Baltic Ports.
