Blue plaque in the context of "Belgravia"

Neal's Yard is a small alley in London's Covent Garden between Shorts Gardens and Monmouth Street which opens into a courtyard. It is named after the 17th-century developer Thomas Neale.

In 1976, Michael Palin and Terry Gilliam bought offices at 11 Neal's Yard, and alternative activist and entrepreneur Nicholas Saunders established the bulk Whole Food Warehouse; he had bought 2 Neal's Yard, a derelict warehouse previously used by the former Covent Garden fruit and vegetable market, for £7,000 a few years earlier. From this success, grew other enterprises in other buildings such as Neal's Yard Apothecary (now known as Neal's Yard Remedies), Neal's Yard Bakery, Monmouth Coffee Company and Neal's Yard Dairy,

English Heritage (officially the English Heritage Trust) is a charity that manages over 400 historic monuments, buildings and places. These include prehistoric sites, a battlefield, medieval castles, Roman forts, historic industrial sites, listed ruins, and architecturally notable English country houses.

The charity states that it uses these properties to "bring the story of England to life for over 10 million people each year". Within its portfolio are Stonehenge, Dover Castle, Tintagel Castle, and the "best-preserved" parts of Hadrian's Wall. English Heritage also manages the London blue plaque scheme, which links influential historical figures to particular buildings.

Smithson Tennant FRS (30 November 1761 – 22 February 1815) was an English chemist. He is best known for his discovery of the elements iridium and osmium, which he found in the residues from the solution of platinum ores in 1803. He also contributed to the proof of the identity of diamond and charcoal. The mineral tennantite is named after him.

221B Baker Street is the London address of the fictional detective Sherlock Holmes, created by author Sir Arthur Conan Doyle. In the United Kingdom, postal addresses with a number followed by a letter may indicate a separate address within a larger, often residential building. Baker Street in the late 19th century was a high-class residential district, and Holmes's apartment would probably have been part of a Georgian terrace.

The residence was introduced in the novel A Study in Scarlet (1887). At the time the Holmes stories were published, addresses in Baker Street did not go as high as 221. Baker Street was later extended, and in 1932 the Abbey National Building Society moved into premises at 219–229 Baker Street. For many years, Abbey National employed a full-time secretary to answer mail addressed to Sherlock Holmes. In 1990, a blue plaque signifying 221B Baker Street was installed at the Sherlock Holmes Museum, situated elsewhere on the same block, and there followed a 15-year dispute between Abbey National and the Holmes Museum for the right to receive mail addressed to 221B Baker Street. Since the closure of Abbey House in 2005, ownership of the address by the Holmes Museum has not been challenged, despite its location between 237 and 241 Baker Street. Its postal code is NW1 6XE.

A four-minute mile is the completion of a mile run (1.609 km) in four minutes or less. It translates to an average speed of 15 miles per hour (24 km/h). It is a standard for male professional middle-distance runners in several countries.

The first four-minute mile is usually attributed to the English athlete Roger Bannister, who ran it in 1954 at age 25 in 3:59.4. The mile record has since been lowered by 16.27 seconds. According to World Athletics statistics, the "four-minute barrier" has been broken by just over 2,000 athletes. The record for the fastest time stands at 3:43.13, achieved by the Moroccan athlete Hicham El Guerrouj, at age 24, in 1999. There has not yet been a woman who has run a four-minute mile.

The Holy Trinity Church is an Anglican church located in Clapham, London. Completed in 1776, it was the base for the so-called Clapham Sect who worshipped there. It is located on the north side of Clapham Common and is a Grade II* listed building.

The Clapham Sect, or Clapham Saints, were a group of social reformers associated with Holy Trinity Clapham in the period from the 1780s to the 1840s. Despite the label "sect", most members remained in the established (and dominant) Church of England, which was highly interwoven with offices of state.
