road which became Montpelier Place. (The four-storey houses of Belvedere Terrace were built on her behalf in the grounds of Belvedere House in about 1852.) Brighton was connected to the railway network in 1840 when a line to Shoreham-by-Sea opened, followed in 1841 by the completion of the link to London. This stimulated growth even further, and the 1840s were a boom period for Montpelier. (Brighton as a whole grew rapidly in the 1840s—between 1841 and 1851, 2,806 new houses were built compared to 437 for the preceding decade—but the effect was greater in Montpelier because the station was close by at the foot of West Hill.) During the 1840s, Montpelier Villas and Montpelier Crescent were laid out, several houses were built in Clifton Road, Montpelier Road and Montpelier Terrace were fully built up, Upper North Street became an important route lined with "modest yet grandly treated" houses, the "very attractive composition" of Clifton Terrace was built (it was finished in 1847), Victoria Street was laid out with bay-fronted terraced houses, and Windlesham House was constructed near The Temple. This became the New Sussex Hospital in 1921 after alterations by the Clayton & Black architecture firm, but is now flats called Temple Heights. Developments in the 1850s included Powis Square, Villas and Road, Norfolk Terrace and Vernon Terrace. The Powis area took its name from property developer John Yearsley, who was from Welshpool in Powys. Yearsley bought several acres of land on a leasehold basis from the Kemp family in 1846; he acquired the freehold soon after. (Thomas Read Kemp died in France in 1844, seven years after leaving Brighton to escape his debts.) Land was also acquired and developed by the prominent Hallett, Wisden, Baring and Faithfull families. (The Baring baronets were related to Thomas Read Kemp by marriage; Henry Faithfull, who worked with Yearsley to develop the Powis area, was the brother of MP George Faithfull; and Thomas and John Wisden were prolific builders.) Denmark Terrace, a continuation of Vernon Terrace, was erected in the 1860s; at its south end it met Temple Gardens, the road on which The Temple stood. Also of the 1860s were parts of Norfolk Road (where development had started 30 years before), St Michael's Place (1868–69) with terraced houses "impressive in their length and height", and some infill development in Montpelier Terrace, Clifton Place, Powis Road and Vernon Terrace. Montpelier's residential development was
