Question: Royal Crescent is a crescent-shaped terrace of houses has been placed on what?
Context: A crescent is an architectural structure where a number of houses, normally terraced houses, are laid out in an arc to form of a crescent shape.  A famous historic crescent is the Royal Crescent in Bath, England. No. 1 Royal Crescent is the first building at the eastern end of the Royal Crescent in Bath, Somerset, and is of national architectural and historic importance.  It is currently the headquarters of the conservation charity, the Bath Preservation Trust, and also operates as a public "historic house" museum displaying authentic room sets, furniture, pictures and other items illustrating Georgian domestic life both 'above stairs' and 'below stairs'.  The house was the subject of a major renovation project during 2012 and 2013 (The Whole Story Project) which reunited No. 1 with its original service wing at No. 1A, from which it had been separated during the 20th century. The Royal Crescent is a row of 30 terraced houses laid out in a sweeping crescent in the city of Bath, England.  Designed by the architect John Wood, the Younger and built between 1767 and 1774, it is among the greatest examples of Georgian architecture to be found in the United Kingdom and is a Grade I listed building.  Although some changes have been made to the various interiors over the years, the Georgian stone façade remains much as it was when it was first built. Montpelier Crescent is a mid 19th-century crescent of 38 houses in the Montpelier suburb of Brighton, part of the English coastal city of Brighton and Hove.  Built in five parts as a set-piece residential development in the rapidly growing seaside resort, the main part of the crescent was designed between 1843 and 1847 by prominent local architect Amon Henry Wilds and is one of his most distinctive compositions.  Extra houses were added at both ends of the crescent in the mid-1850s.  Unlike most other squares, terraces and crescents in Brighton, it does not face the sea—and the view it originally had towards the South Downs was blocked within a few years by a tall terrace of houses opposite.  Montpelier was an exclusive and "salubrious" area of Brighton, and Montpelier Crescent has been called its "great showpiece".  Wilds's central section has been protected as Grade II* listed, with the later additions listed separately at the lower Grade II.  The crescent is in one of the city's 34 conservation areas, and forms one of several "outstanding examples of late Regency architecture" within it. The Royal Crescent is a Grade II* listed street in Holland Park, west London, England, consisting of two curved facing terraces in a crescent shape.  The crescent is located on the north side of Holland Park Avenue, west of Addison Avenue, and to the east of the Holland Park Roundabout. Vernon Terrace is a mid 19th-century residential development in the Montpelier suburb of Brighton, part of the English coastal city of Brighton and Hove.  Construction of the first section started in 1856, and the 37-house terrace was complete in the early 1860s.  Architecturally, the houses divide into five separate compositions, although all are in a similar late Regency/Italianate style.  This was characteristic of houses of that era in Brighton, and especially in the Montpelier area—where the Regency style persisted much later than elsewhere.  Standing opposite is the landmark Montpelier Crescent, which had a view of the South Downs until Vernon Terrace blocked it.  Three groups of houses in the terrace have been listed at Grade II by English Heritage for their architectural and historical importance. Royal Crescent is a crescent-shaped terrace of houses on the seafront in Brighton, part of the English city of Brighton and Hove.  Built in the late 18th and early 19th century as a speculative development on the open cliffs east of Brighton by a wealthy merchant, the 14 lodging houses formed the town's eastern boundary until about 1820.  It was the seaside resort's first planned architectural composition, and the first built intentionally to face the sea.  The variety of building materials used include black glazed mathematical tiles—a characteristic feature of Brighton's 18th-century architecture.  English Heritage has listed the crescent at Grade II* for its architectural and historical importance.  An adjacent five-storey building, formerly the Royal Crescent Hotel but now converted into flats with the name Royal Crescent Mansions, is listed separately at Grade II. A listed building or listed structure, in the United Kingdom, is one that has been placed on the Statutory List of Buildings of Special Architectural or Historic Interest. Crescent City (Chetco-Tolowa: "Taa-’at-dvn", Yurok: "Kohpey", Wiyot: "Daluwagh" ) is the county seat and only incorporated city in Del Norte County, California.  Named for the crescent-shaped stretch of sandy beach south of the city, Crescent City had a total population of 7,643 in the 2010 census, up from 4,006 in the 2000 census.  The population includes inmates at Pelican Bay State Prison, also within the city limits, and the former census-designated place Crescent City North annexed to the city.  The city is also the site of the Redwood National Park headquarters, as well as the historic Battery Point Light.  Due to the richness of the local Pacific Ocean waters and the related catch, and ease of access, Crescent City Harbor serves as home port for numerous commercial fishing vessels. The Crescent was a part-completed, Regency-style terrace in central Birmingham, England, first proposed in 1788, started and discontinued in 1795, and finally demolished in the mid- to late 1960s.  Like other late 18th and early 19th century crescent terraces in Britain and Ireland, it took its inspiration from The Crescent (later Royal Crescent), Bath designed by John Wood the Younger and built 1767 to 1774.
