Llanidloes once had thriving wool, lead mining and flannel industries, all making use of freely available water-power from the rivers Severn and Clywedog. Whilst no longer buzzing with the various industries of times past, Llanidloes still retains a vibrancy and life of its own. Llanidloes welcomes visitors and not for nothing is it known as ""the friendly town"". Llanidloes town has a wealth of historical buildings including the Old Market Hall, built in about 1600 and standing at the intersection of the town's four main streets. The River Severn, together with the Clywedog, have long formed the life-blood of the town and, these days, are central to an extensive network of footpaths and bridleways that take in some of the most beautiful views in Mid Wales.
