- Mayfair
- It took its name from a May fair that ran here from 1686 until 1764, when it grew too rowdy for the neighbourhood the Grosvenor family was building around it. The Grosvenor family developed the streets around Grosvenor Square from the 1720s, and their estate still owns much of the ground it stands on.
- City of London
- Barely more than a square mile, 2.9 square kilometres inside the old Roman and medieval walls, it has stayed a separate local authority from the 32 boroughs around it. Fewer than 9,000 people live inside it, but more than 500,000 work there on weekdays, in the banks and insurance offices packed into a street pattern the Great Fire never straightened.
- Westminster
- The seat of national government since the Middle Ages, with the parliament sitting beside the river and the abbey behind it. Buckingham Palace stands at the western edge, and the district runs from the ministries on Whitehall down to the royal parks.
- Covent Garden
- A fruit and vegetable market ran here from 1654 until 1974, when the lorries could no longer get through the streets around it and the whole trade moved out to Nine Elms, 5 kilometres southwest. The Royal Opera House and the London Transport Museum sit on the same square, laid out by Inigo Jones in the 1630s as one of the first planned piazzas in London.
- Notting Hill
- Portobello Road has held a street market since the 19th century, groceries first and antiques since the late 1940s, and it still runs the length of the hill on a Saturday. The Notting Hill Carnival began in 1966, out of the Caribbean families who had settled these streets after the war.
- Shoreditch
- England's first purpose-built playhouses stood here in the 1570s, until the companies crossed the river to Southwark. Furniture makers worked these streets through the 19th century, and bars and clubs moved into the empty warehouses from the 1990s.
