Adelphi Iron Works was bounded by Adelphi Street, Peru Street, John Dalton Street and Cleminson Street. The 1848 O.S. map shows the site to have been largely occupied by five filtering ponds used by the Adelphi Dye Works, Adelphi Print Works, and Swimming Baths. There was a terrace of 12 houses between the ponds and Peru Street. These houses were still shown on the 1922 O.S. map. To the east of the ponds was an area of land used as a brick croft, and marked as the site of Bank Hall.
At some point the premises expanded to include property on the west side of Adelphi Street.
Latterly the expanded premises were used by Sir James Farmer Norton and Co to produce specialised machinery. The houses on Peru Street were demolished, and buildings on the opposite side of Peru Street housed the Mechanical Engineering Dept of the University of Salford. At the corner of Adelphi Street and (Upper) Cleminson Street stood a pleasant little pub called the Brewery Tavern, popular with engineering workers, staff from the nearby Salford Royal Hospital, and students. The 1848 map shows the pub as the Adelphi Street Brewery. By 2010 all had been cleared to provide Salford with more derelict land.
