Royal Leamington Spa, commonly known as Leamington Spa or simply Leamington (/ˈlɛmɪŋtən/ ), 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 examples of Regency architecture, particularly in parts of the Parade, Clarendon Square and Lansdowne Circus. The town also contains several large public parks, such as Jephson Gardens, the Royal Pump Room Gardens and Victoria Park.
