Although Salford lacks the number of Grade II* (and above) listed buildings accorded to its neighbour (Manchester), it does possess a wide range of both classical and modern architecture, as well as some unique structures, including the 19th-century Barton Swing Aqueduct. One of Salford's oldest buildings is the Grade I listed Ordsall Hall, a Tudor mansion and former stately home in nearby Ordsall. It dates back over 750 years, although the oldest surviving parts of the present hall were built in the 15th century. Kersal Cell is a Grade II* listed 16th-century timber-framed manor house, currently in use as a private residence. Closer to the centre of the settlement, the tower of the Church of the Sacred Trinity dates from 1635, the main building from 1752. It was restored between 1871 and 1874.
