Shropshire: The `blue remembered hills' of Shropshire form one of the most beautiful, peaceful and underrated areas of Britain. The gentle terrain and the low population density make it perfect cycling or open walking country. The county's capital, Shrewsbury, is probably the finest Tudor town in England, famous for its half-timbered buildings and winding medieval streets. Nearby Wroxeter boasts the ruins of Viroconium, the fourth-largest city in Roman Britain. Ironbridge, south of Telford, was the Silicon Valley of the Industrial Revolution, and the Ironbridge Gorge Museum is Britain's finest museum of industrial archaeology.
