Hertfordshire - online puzzles

Hertfordshire ( (listen); often abbreviated Herts) is one of the home counties in southern England. It is bordered by Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it is placed in the East of England region.

In 2013, the county had a population of 1,140,700 in an area of 634 square miles (1,640 km2). The four towns that have between 50,000 and 100,000 residents are Hemel Hempstead, Stevenage, Watford and the only city in the county, St Albans. Hertford, once the main market town for the medieval agricultural county, derives its name from a hart (stag) and a ford, used as the components of the county's coat of arms and flag. Elevations are high for the region in the north and west. These reach over 800 feet (240 m) in the western projection around Tring which is in the Chilterns. The county's borders are approximately the watersheds of the Colne and Lea; both flowing to the south ; each accompanied by a canal. Hertfordshire's undeveloped land is mainly agricultural and much is protected by green belt.
