The historic counties of Montgomeryshire, Radnorshire and Breconshire are described in this final volume of the Buildings of Wales series, expanded and revised from the first edition of 1979. Prehistoric hill-forts and standing stones, Roman encampments, Early Christian monuments, ruined castles and the enigmatic remains of early industry enhance the landscapes of this wild and beautiful region. Atmospheric medieval churches survive in quantity, together with diverse Nonconformist chapels. Vernacular traditions are represented by robust medieval cruck-framed houses, and by the manor houses and farmhouses of the Tudors and Stuarts. Other highlights include Montgomery, with its beguiling Georgian heritage, the Victorian spa at Llandrindod Wells, and Powis Castle, with its Baroque interiors and terraced gardens.
