names are also used interchangeably, and some sources make further distinctions: the area around Powis Grove, Powis Villas, Powis Road and St Michael and All Angels Church is called Powis in one study of the area. Although Montpelier first appears as the name of the area on a map of 1824, this still makes it the earliest Montpelier in England—predating those in Bristol, Cheltenham and elsewhere in taking and adapting the name of the French spa resort Montpellier. The town was popular with rich English people in the 18th century for convalescence: it had an excellent climate and good medical facilities. The term "Montpelier Estate" is sometimes used for the area as a whole.
