Royal Tunbridge Wells (often shortened to Tunbridge Wells) is a large town and Borough in west Kent, England, about 40 miles (64 km) south-east of central London by road, 34.5 miles (55.5 km) by rail.[1] The town is close to the border of the county of East Sussex. It is situated at the northern edge of the High Weald, the sandstone geology of which is exemplified by the rock formations at the Wellington Rocks and High Rocks. The town came into being as a spa in Georgian times and had its heyday as a tourist resort under Beau Nash when the Pantiles and its chalybeate spring[2] attracted visitors who wished to take the waters. Though its popularity waned with the advent of sea bathing, the town remains popular and derives some 30% of its income from the tourist industry.[3] The town has a population of around 56,500[4] and is the administrative centre of Tunbridge Wells Borough and the UK parliamentary constituency of Tunbridge Wells. In the United Kingdom Royal Tunbridge Wells has a reputation as being the archetypal conservative "Middle England" town, a stereotype that is typified by the fictional letter-writer "Disgusted of Tunbridge Wells".[5]
