God’s House Tower is a medieval gatehouse and gun tower at the south-east corner of Southampton’s old town walls, later used as the town gaol and now run as an arts and heritage venue by the charity ‘a space’ arts. Its oldest part, God’s House Gate, dates from 1189, and the tower itself was built in 1400 to house gunpowder and cannon, according to the venue. Entry to the building, café and galleries is free, while the Stories Behind the Stones exhibition, which climbs the tower to its rooftop, costs £7 for adults and is free for children.

History of God’s House Tower

God’s House Gate, the oldest part of the building, was built in 1189 to give access to the Platform Quay and guard the town from attack by sea, according to God’s House Tower’s own history. It took its name from the nearby God’s House Hospital, which the Historic England list entry describes as a hospital for poor travellers. The listing records that the gate was also known as the Saltmarsh Gate, that it has an arched gateway with a double portcullis, and that the tower above the gate was called Lambcote Tower and used as a prison.

Southampton Town Walls

Southampton’s town walls were ordered by Edward III after French raiders pillaged the undefended town in 1338, according to God’s House Tower, and the townspeople had to pay for them. The venue records that the raiders set fire to houses and plundered cellars full of wine and wool. The Tower at God’s House was then built in 1400 at the south-eastern corner of the new walls, as a lookout across the Solent and a store for gunpowder and cannons. It remained an important defensive structure for the next 300 years. The gate and tower are now protected together as a scheduled monument, a site of national importance protected by law.

By the 17th century, with attack from the sea no longer a threat, the tower fell into disrepair. In 1760 plans were drawn up to turn it into God’s House Gaol, which held three prisons in one building: the Bridewell (a house of correction for minor offenders), the Felons’ prison and the Debtors’ gaol. God’s House Tower records that the gaol, built over the town ditches, was always cold and damp, with disease rife. Prisoners were held in chains and set to hard labour, turning a hand-cranked mill in the prison yard or picking oakum, pulling old tarred rope apart into loose fibre. They were moved out in 1855, after which part of the building served as a temporary mortuary, until the Southampton Harbour Board rented it as a warehouse in 1876.

In the 1960s the building became the city’s archaeology museum, gaining Brutalist concrete staircases and parquet floors. The museum closed in 2011, and in 2019, after a four-year restoration, it reopened as an arts and heritage venue run by ‘a space’ arts. God’s House Gate is Grade I listed, the highest grade of protection for a historic building in England, according to its listing. It is one of many castles and historic attractions worth seeking out in England.
