Royal Leamington Spa, commonly known as Leamington Spa or simply Leamington, is a spa town and civil parish in Warwickshire, England. Originally a small village called Leamington Priors, it grew into a spa town in the 18th century following the popularisation of its water which was reputed to have medicinal qualities. In the 19th century, the town experienced one of the most rapid expansions in England. It is named after the River Leam, which flows through the town.
The town contains especially fine ensembles of Regency architecture, particularly in parts of the Parade, Clarendon Square and Lansdowne Circus.
In 2019 Leamington had an estimated population of 52,213. Leamington is adjoined with the neighbouring towns of Warwick and Whitnash, and the village of Cubbington; together these form a conurbation known as the "Royal Leamington Spa Built-up area" which in 2011 had a population of 95,172.
Leamington lies around 8 miles south of Coventry, 20 miles south-east of Birmingham, and 81 miles north-west of London.
