a house whose site is believed to be near the present North Gate of the Royal Pavilion; a terrace of nine houses, Marlborough Row, existed there until 1820, when all but one were demolished when the Royal Pavilion estate was redeveloped. (The surviving house, number 8, is now called North Gate House and stands alongside the North Gate.) Even when the Royal Pavilion, the Prince's Brighton residence, was completed in 1787, the couple never stayed in the same house together. Under pressure to undertake a legal marriage to produce an heir, they divorced in 1794 and the Prince married Caroline of Brunswick; but they soon separated, and in June 1800 Mrs Fitzherbert and the Prince were reunited. The royal couple sought a site for a permanent home for Mrs Fitzherbert, and in 1804 she commissioned the Prince's favoured architect William Porden to design and build a house on the west side of Old Steine, next to Marlborough House, to replace a Mr Tuppen's lodging house. His design included a large colonnade across the front in an Egyptian style; this only lasted until the next year, when a storm destroyed it. He redesigned the façade in the Italianate style instead, with verandahs on both storeys. Maria Fitzherbert lived at Steine House until her death on 27 March 1837, after which she was buried at St John the Baptist's Church, Brighton's oldest surviving Roman Catholic church. Throughout her life in Brighton, she was treated extremely well by high society (statesman and writer John Wilson Croker remarked that "one reason why she may like this place is that she is treated as queen, at least of Brighton"), and for the first few decades of the 19th century Steine House was the second most important house in Brighton after the Royal Pavilion. Steine House passed through several private owners after 1837, and finally passed out of residential use in the early 1860s when William Forder, a judge, sold it. At this time, a blocked staircase was discovered leading down from the cellar; false rumours abounded that a secret tunnel had been built between the house and the Royal Pavilion, and that the staircase led to this tunnel. It is considered more likely that the stairs gave access to Brighton's sewer network. The building was converted into the Civil and United Services Club, a social club, which required major internal renovations; these were completed in
