City Bridge Trust

The Bridge House Estates is a charitable trust, established in 1282 by the City of London Corporation in London, England. It was originally established to maintain London Bridge and, subsequently, other bridges. Funded by bridge tolls and charitable donations, the trust acquired an extensive property portfolio which made it more than self-sufficient. As well as maintaining the bridges, the estates also makes other charitable grants through the City Bridge Trust, their grant-making arm.

Since it was established, the trust has maintained, and on several occasions replaced, London Bridge. The trust also built Blackfriars Bridge and Tower Bridge, and purchased Southwark Bridge from the toll-exacting private company that built it. Most recently it took over ownership and maintenance of the new pedestrian-only Millennium Bridge, having provided a large amount of the funding for its construction.

Until 1995, the trust was only permitted to use its income for expenditure on its bridges. However, with a surplus of income over expenditure, a cy-près scheme was adopted in that year to allow any surplus income to be used for other charitable purposes benefiting Greater London. These grants are made though the City Bridge Trust.

The Trust took its name from Bridge House, which was the administrative and maintenance centre of Old London Bridge located on the south bank of the River Thames, near the site of St Olave's Church (since replaced by St Olaf House in Tooley Street). The site, now covered by the London Bridge Hospital and the Cotton's Centre, was constituted of at least two properties in Southwark. The first was that of Peter de Colechurch the warden of the bridge from 1163 and probably a monastic dwelling. The second property was the house left by will of Henry Fitz Ailwyn, first named Mayor of London, in 1215.

The bridge became part of the City's jurisdiction from 1282, and this led to the City attempting to extend control over Southwark, succeeding in acquiring the 'vill of Southwark' alias the Guildable Manor in 1327.
