Mitre Square

The Holy Trinity Priory, also known as Christchurch Aldgate, was a priory of Austin canons (Black Canons) founded around 1108 by Queen Matilda of England, wife of King Henry I, near Aldgate in London. The queen received advice and help in the foundation from Anselm of Canterbury, the Archbishop of Canterbury. The house was founded with clergy from St Botolph's Priory in Colchester, and the first prior was Norman, who was the queen's confessor. By 1115 the entire soke, or liberty of East Smithfield (including the ward of Portsoken) was given by the Knighten Guilde to the church of Holy Trinity within Aldgate. The prior of the abbey was then to sit as an ex officio Alderman of London.Matilda of Boulogne continued the close relationship between queenship and the priory. Two of her children were buried here and she took the prior as her confessor. In the 12th century the priory had a reputation as a centre of learning under Prior Peter of Cornwall.Thomas Pomerey is named as the prior of the house & church of Holy Trinity within Algate, in 1460. The priory was dissolved in February 1532 when it was given back to King Henry VIII of England. The buildings and land associated with the priory were given, or sold, to prominent courtiers and City merchants. None of the buildings survive today except for some pointed arches within the office building on the corner of Aldgate and Mitre Street. Mitre Street itself follows roughly the line of the nave of the priory church, while Mitre Square corresponds roughly to the former cloister. Some account of the Priory is given by John Stow, and in the revised Monasticon.

Aldgate () was a gate in the former defensive wall around the City of London. It gives its name to Aldgate High Street, the first stretch of the A11 road, which included the site of the former gate. The area of Aldgate, the most common use of the term, is focused around the former gate and the High Street and includes part of the city and parts of the London Borough of Tower Hamlets. It is 2.3 miles (3.7 km) east of Charing Cross. There is also an Aldgate Ward of the City of London. The Ward is of ancient origin, but intramural, so almost entirely distinct from the area around Aldgate High Street, which is mostly outside the line of the London Wall.

The St Botolph Building is a commercial office in Houndsditch, central London, opened in 2011 and designed by Grimshaw Architects. It is one of a number of landmark buildings recently delivered or in development to the East of the Gherkin in the City of London ward of Aldgate, which together with the wards of Langbourn, Cornhill and Lime Street forms the centre of the UK insurance industry. Two of the three main tenants, Jardine Lloyd Thompson and Lockton, are businesses with a substantial insurance broking component, which are therefore reliant on close proximity to the Lloyd's building and the globally-significant London market in insurance contracts that focuses on Lloyd's of London. The third main tenant, Clyde & Co, also has insurance ties as one of the largest insurance and reinsurance law firms in the world.

Lloyd's Register Group Limited (LR) is a technical and professional services organisation and a maritime classification society, wholly owned by the Lloyd’s Register Foundation, a UK charity dedicated to research and education in science and engineering. The organisation dates to 1760. Its stated aims are to enhance the safety of life, property, and the environment, by helping its clients (including by validation, certification, and accreditation) to improve the safety and performance of complex projects, supply chains and critical infrastructure. In July 2012, the organisation converted from an industrial and provident society to a company limited by shares, named Lloyd’s Register Group Limited, with the new Lloyd’s Register Foundation as the sole shareholder. At the same time the organisation gave to the Foundation a substantial bond and equity portfolio to assist it with its charitable purposes. It will benefit from continued funding from the group’s operating arm, Lloyd’s Register Group Limited. In 2020, Lloyd's Register sold its Energy business and in 2021 sold its Business Assurance & Inspection Services division. Lloyd's Register is unaffiliated with Lloyd's of London, but emerged from the same professional and social circles that historically met at Lloyd's Coffee House, from which both organisations took their name.

The road follows the line of the outside edge of the ditch which once ran outside the London Wall. The road Houndsditch took its name from the section of ditch between Bishopsgate and Aldgate. The name may derive from the widespread dumping of rubbish in this stretch of ditch; relating to the dumping of dead dogs, or the scavenging of the waste by feral dogs.
