The Cotswolds (/ˈkɒtswoʊldz, ˈkɒtswəldz/ KOTS-wohldz, KOTS-wəldz) is a region of South West and South East England with small parts extending into the West Midlands, along a range of wolds or 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 highest point is Cleeve Hill at 1,083 ft (330 m), just east of Cheltenham. The predominantly rural landscape contains stone-built villages, towns, stately homes and gardens featuring the local stone.
A large area within the Cotswolds has been designated as a National Landscape (formerly known as Area of Outstanding Natural Beauty, or AONB) since 1966. The designation covers 787 square miles (2,038 km), with boundaries roughly 25 miles (40 km) across and 90 miles (140 km) long, stretching south-west from just south of Stratford-upon-Avon to just south of Bath, making it the largest National Landscape area and England's third-largest protected landscape.
