on the first floor of the Regency Square elevation have architraves which join the sill of the second-floor window directly above. There are stuccoed panels between these windows as well, and some of the north-facing windows also have panelling in their spandrels. A tall parapet rises above the cornice. Bollards Two cast-iron bollards in the passageway outside the Regency Tavern are also listed at Grade II. They were erected in the mid-19th century, and are fluted along their length. One has the name of its local founder at the bottom. On 31 December 2012, one was broken and was replaced with a smaller plain bollard instead of a facsimile, causing controversy locally. Social aspects Regency Square was a prestigious, high-class development, attracting the social elite. The square gradually lost its prestige status after World War I as hotels started to move in. Although most of the houses had become hotels by the mid-20th century, the majority have since been converted into flats and the square today is overwhelmingly residential. Military bands gave a performance in the garden in 1831 and 1849, and again in 1904 at the unveiling of the Royal Sussex Regiment Memorial, but the residents' committees strove to ensure that the garden was mainly a quiet space for residents. In the 1890s, temporary tennis courts were marked out on the lawn. During World War II air-raid shelters were built on the square and an underground car park was built beneath it in 1969. Number 1 Regency Square, later known as St Albans House and now numbered 131 King's Road, is "historically the most interesting house in the square". Amon Henry Wilds designed and built it in 1829, William Izard laid out the interior. The house was one of the most important social venues in Brighton between 1830 and the Duchess's death in 1837. She was born Harriet Mellon in 1777, became an actress, married banker Thomas Coutts in 1815, and inherited his fortune when he died in 1822—thereby becoming England's richest woman. After being courted by many men, she met and married William Beauclerk, the 9th Duke of St Albans, and they became regular visitors to Brighton. From 1830, their prolonged stays at No. 1 Regency Square were so frequent that it was named St Albans House. For the next seven years, it was the venue for lavish balls and extensive feasts, with hundreds of upper-class guests. The
