Worshipful Company of Mercers

Ironmonger Lane is a narrow one-way street in the City of London running southbound between Gresham Street and Cheapside. Ironmonger Lane has maintained the same name since at least the 12th century when it was recorded as Ismongerelane; "isen" was an old form of the word "iron". Its name indicates that it was the once the location of ironmongers; but by the end of the 16th century, when John Stow was writing his Survey of London, the ironmongers of Ironmonger Lane and Old Jewry had moved to Thames Street.Until the Great Fire of London in 1666, Ironmonger Lane was one of only two accesses to the Guildhall (the other being Lawrence Lane), a matter which made the travel of dignitaries difficult as two vehicles could not pass each other. The problem was alleviated after the fire when King Street was added by Christopher Wren to provide an additional access to Cheapside.Thomas Becket is said to have been born on the corner of Cheapside and Ironmonger Lane. The livery hall of the Worshipful Company of Mercers may lie on the same spot; it is a relatively modern building, the first hall having been destroyed in the Great Fire and a second in the Blitz. In the interwar-period, Ironmonger Lane was the seat of several cartels e.g. of the European Rail Makers Association ERMA. The nearest London Underground/Docklands Light Railway station is Bank. The closest mainline railway stations are Cannon Street and Moorgate.

The Hospital of St Thomas of Acre was the medieval London headquarters of the Knights of Saint Thomas. It was founded as a church in 1227 in the parish of St Mary Colechurch, birthplace of the order's patron saint, Saint Thomas Becket. In the 14th century and after it was the main headquarters of the military order.In 1512, the Worshipful Company of Mercers bought from the order a site by the church on which to build their hall, and in 1514 they formally became the patron to the order.In 1538, during the Protestant Reformation, the order was dissolved and the properties were forfeit to the crown, but were subsequently acquired by the Mercers in exchange for various payments, rents, and undertakings.

The Great Conduit was a man-made underground channel in London, England, which brought drinking water from the Tyburn to Cheapside in the City.In 1237 the City of London acquired the springs of the Tyburn and built a small reservoir, a head of water, to help serve the city with a steady, free, flowing supply. Work on the conduit began in 1245. It was much repaired over centuries. It ran towards Charing Cross, along the Strand north of which were fields. It then followed Fleet Street. At Fleet Street most of the city was to the north-east. It then ran along Cheapside (meaning market side, a key retail and general market of the city) where a building housed a great trough/tank and led to a surplus, overflow channel. Citizens from this were at liberty to draw water in small amounts and, greater, for permitted purposes. Wardens were appointed to stem taking too much water, unpermitted taking or diversion, and to repair pipes. Extensions were made leading to other parts of the city. Other conduits were constructed in the 15th century AD (CE). In the 15th century further source was added to the main conduit, from the Westbourne, enabling a new, additional off-tap at Cripplegate: one parish within and one without (outside) a northern gate in ancient, sparsely intact walls. Use of the conduit ceased after the Great Fire of London in 1666.

The church was demolished in 1887, except for the tower and west wall, which remain today.
