Montpelier is an inner suburban area of Brighton, part of the English city and seaside resort of Brighton and Hove. Developed together with the adjacent Clifton Hill area in the mid-19th century, it forms a high-class, architecturally cohesive residential district with "an exceptionally complete character". Stucco-clad terraced housing and villas predominate, but two of the city's most significant Victorian churches and a landmark hospital building are also in the area, which lies immediately northwest of Brighton city centre and spreads as far as the ancient parish boundary with Hove.

Henry Michell Wagner (1792–1870) was a Church of England clergyman who was Vicar of Brighton between 1824 and 1870. He was a descendant of Melchior Wagner, hatmaker to the Royal Family, and married into a wealthy Sussex family who had a longstanding ecclesiastical connection with Brighton. Wagner paid for and oversaw the building of five churches in the rapidly growing seaside resort, and "dominated religious life in the town" with his forceful personality and sometimes controversial views and actions. His son Arthur Wagner (1824–1902) continued the family's close association with Brighton.
