Small, it is bounded by wards: Coleman Street, east; Cheap, south; Cripplegate, north; Aldersgate, west.

[4] The ward is named for Basinghall, the mansion house of the Bassing (or Basing) family, who were prominent in the City beginning in the 13th century.

[1] King Henry III granted Adam de Basing "certain houses in Aldermanbury and in Milk-street; the advowson of the church at Bassings hall; with other liberties and privileges".

St Alphage London Wall, also damaged in the Great Fire but not rebuilt until 1777, was eventually demolished in 1924.

[6] The ward contains a large part of the Guildhall buildings, the main administrative centre for the City of London Corporation.

Aldermanbury has broad pavements and remains a pedestrian link from Gresham Street to the road aspect of, the main successor of, London Wall.
