Turret 7B (Denton Hall Turret or Denton Turret) is located in West Denton opposite East Denton Hall (also known as Bishops House) on West Road. The turret is up to six courses high and is made from sandstone. It is recessed by 5 feet (1.5 m) into a section of the broad part of Hadrian's Wall that measures 65m long. Turret 7B is 13 feet (4.0 m) wide north to south and 14 feet (4.3 m) east to west with a 3 feet 8 inches (1.12 m) wide entrance in its south side. The wall associated with Turret 7B is the furthest east of the known surviving sections.
The turret was first located in 1928 and excavated by the Office of Works in 1929. The excavation discovered a heap of pottery in the centre of the east wall, which has been suggested as the location of a window. Three different levels of floor were found suggesting three stages of occupation of 122–196, 205–295 and 300–367 AD. The original floor was constructed of clay and contained a hearth and a stone box, with a stone bowl on it, the floor had been partially repaired with flagstones. A spearhead and the binding from a shield were discovered within the repair. A building had been constructed over the turret and 18th-century pottery remains associated with this were also found. Another excavation was carried out in 1936. It has been proposed that Turret 7B was one of the structures garrisoned by soldiers based at the Condercum fort in Benwell.
The turret was placed under English Heritage guardianship by 1971. The turret and attached wall are maintained as a single property by English Heritage (known as "Denton Hall Turret"). The organisation operates the property as an open access site with no entrance fees. Turret 7B was the first site on Hadrian's Wall visited in Guy de la Bedoyere's BBC Radio 4 series The Romans in Britain.
