The county of Somerset can trace its origins back to Anglo-Saxon England, when it was a distinct part of the kingdom of Wessex, although the history of its peoples stretches back much further. Much of the county is agricultural and its wealth in the Middle Ages is seen today in Wells Cathedral, churches and the remains of abbeys. The north-east of the county was also a coal-mining area and Bridgwater became an important port in the Industrial Revolution. Today the county is as well known for the annual Glastonbury Festival as it is for its many tourist attractions.

In 50 Gems of Somerset, author Andrew Powell-Thomas explores the many places and their history that make this part of the south-west of England so special. It includes Roman remains, castles, magnificent houses and churches, and historic towns, as well as present-day festivals and events. There is also a living heritage of military, transport and industry and natural attractions that include moors, hills, coastline, parks and many other treasures. Alongside the justly famous sites such as Cheddar Gorge and Wookey Hole the author includes many lesser-known gems that are equally deserving of attention.
