The Old Market Hall is the building that makes Llanidloes stick in the memory. It stands at the crossing of the town's main streets, with a stone base, timber frame, and upper room that once served as a wool market, court, meeting room, and museum.
It is small, but it carries a lot of history. The open cobbled ground floor recalls the weekly market, while the timber-frame exhibition explains how these Welsh market halls were built and why this one survived.
