With justification, Cheltenham claims to be Britain`s most complete Regency town, and all the architecture of modern development has to be sympathetic with this image. In 1716 a mineral spring was discovered in a village along the Cotswold edge. Within a century Cheltenham had developed into one of the great spa towns of Europe. The town’s wide streets and tree-lined avenues were built at the beginning of the 19th century; distinctive streets include Landsdowne Crescent, with its convex curve, and Royal Crescent, whose curve is concave. The Promenade has Greek terraces on one side, smart shops on the other, and at the top end a statue of Neptune, commanding a fine fountain. The Rotunda, looking like the Pantheon in Rome, was the Montpellier Spa. The composer Gustav Holst was born in 1874 at Number 4, Clarence Road - his Regency house is now a museum. It’s a fine modern town, too - the High Street is pedestrianised and has the full range of national stores and fashionable shops. There are three annual Cheltenham festivals: music in July, literature in August, and the national hunt horseracing in March.
