The Cotswolds is a region of central South West England, along a range of rolling hills that rise from the meadows of the upper River Thames to an escarpment above the Severn Valley and the Vale of Evesham. The area is defined by the bedrock of Jurassic limestone that creates a type of grassland habitat that is quarried for the golden-coloured Cotswold stone. It lies across the boundaries of several English counties: mainly Gloucestershire and Oxfordshire, and parts of Wiltshire, Somerset, Worcestershire, and Warwickshire. The predominantly rural landscape contains stone-built villages, towns, stately homes and gardens featuring the local stone.
