This fully-illustrated guide to Shropshire treats each city, town, and village in a detailed gazetteer and includes a variety of helpful maps, plans, and indexes along with an illustrated glossary. The book is an invaluable reference work on the appealing and unspoiled county of Shropshire, where many historic towns, including Shrewsbury and Ludlow, are especially plentiful in Georgian and timber-framed buildings. Shropshire boasts the Cistercian abbey of Buildwas and many important country houses, including the 13th-century fortified mansions at Acton Burnell and Stokesay; John Nash's Italianate villa at Cronkhill; and Norman Shaw's splendid Late Victorian mansion at Adcote. Shropshire is also home to numerous prehistoric hill-forts and the Roman town at Wroxeter as well as Coalbrookdale's spectacular bridge, the first in the world to be built of iron. The unspoiled county of Shropshire is among the most appealing in England for lovers of architecture. The county's many historic towns, of which Shrewsbury and Ludlow are the largest, are especially plentiful in Georgian and timber-framed buildings. Shropshire's villages, intriguingly varied in plan and building materials, reflect the diverse landscape of plains, hills and moorland and the rich and complex underlying geology. The Cistercian abbey of Buildwas is the finest of several notable monastic ruins, and outstanding medieval parish churches and castles are also numerous. Many of the country houses have a central place in the story of English architecture: the fortified mansions at Acton Burnell and Stokesay, thirteenth-century design at its most sophisticated; the vigorous Baroque houses of John Prince and Francis Smith; John Nash's Italianate villa at Cronkhill, looking like something in a Claude painting; Norman Shaw's splendid Late Victorian mansion at Adcote. Shropshire is also unrivalled for its early industrial remains, including the spectacular bridge at Coalbrookdale, the first in the world to be built of iron. More ancient cultures are represented by the numerous prehistoric hill-forts and the celebrated Roman town at Wroxeter. Each city, town or village is treated in a detailed gazetteer. A general introduction provides a historical and artistic overview. Numerous maps and plans, over a hundred new colour photographs, full indexes and an illustrated glossary help to make this book invaluable as both reference work and guide.
This book is an introduction to theory in archaeology – but with a difference. Archaeological Situations avoids talking about theory as if it was something you apply but rather as something embedded in archaeological practice from the start. Rather than see theory as something worked from the outside in, this book explores theory from the inside out, which means it focuses on specific archaeological practices rather than specific theories. It starts from the kinds of situations that students find themselves in and learn about in other archaeology courses, avoiding the gap between practice and theory from the very beginning. It shows students the theoretical implications of almost everything they engage in as archaeologists, from fieldwork, recording, writing up and making and assessing an argument to exploring the very nature of archaeology and justifying its relevance. Essentially, it adopts a structure which attempts to pre-empt one of the most common complaints of students taking theory courses: how is this applicable? Aimed primarily at undergraduates, this book is the ideal way to engage students with archaeological theory.
