Hampshire is England's most militarised county — the home of the Royal Navy at Portsmouth, the British Army at Aldershot and a WWII coastal defence network that runs the full length of the Solent shore. Its abandoned places carry five centuries of that military weight: the oldest purpose-built Naval hospital in Britain closed after 256 years of service, a Georgian country house damaged by WWII military requisition and the Cold War infrastructure of a county that was always on the front line of British defence planning. Here are 5 of the best abandoned places in Hampshire, selected from our Abandoned Places Map UK — 640+ GPS locations across England, Scotland, Wales and Ireland.
Why Hampshire Is a Hidden Gem for Urban Exploration
Hampshire's military heritage creates an urbex landscape of extraordinary depth — the layering of Tudor coastal artillery, Napoleonic army camps, Victorian Palmerston forts, WWI training grounds and WWII defences creates a palimpsest of military abandonment that few English counties can match. The rural Hampshire hinterland behind the M27 adds a country house dereliction layer that most visitors never reach; the New Forest's isolation has preserved several abandoned estate structures in remarkable atmospheric condition.
1. Royal Hospital Haslar – Gosport, Hampshire — 1753 Royal Naval Hospital, Oldest Purpose-Built Naval Hospital in Britain, Closed 2009, Grade II* Listed (Known Location)
Royal Hospital Haslar at Gosport is the oldest purpose-built Naval hospital in Britain — opened in 1753 to treat sailors of the Royal Navy, serving through every major naval conflict from the Seven Years War to the Falklands before finally closing in 2009. The extraordinary Georgian brick complex, the colonnaded courtyard, the chapel and the ward buildings decay in progressive atmospheric abandonment. The Grade II* listed status has not prevented significant deterioration; the combination of the 256-year operational history and the scale and quality of the Georgian architecture make Haslar one of the most historically significant and most atmospherically extraordinary abandoned buildings in Hampshire.

2. Westbury House – Bishop's Waltham, Hampshire — Georgian Country House, Palladian Style, WWII Military Requisition, Abandoned Since Care Home Closure, Documented on 28DaysLater (Known Location)
Westbury House near Bishop's Waltham is a Georgian country house built in the Palladian style — rebuilt in brick after a fire in 1904, later serving as a boys' preparatory school before becoming a care home until it closed in the 2010s after being rated inadequate. The house has been abandoned since closure, with the original Georgian interior layout, the staircase and the principal rooms in progressive atmospheric decay. Documented on 28DaysLater as one of the most accessible and most atmospherically complete abandoned country houses in Hampshire.

3. RAF Lasham – Lasham, Hampshire — 1940s WWII Airfield, Glider Station Since 1952, Derelict Original Station Buildings Including Watch Office, Rural Hampshire (Known Location)
RAF Lasham in rural Hampshire was built as a WWII operational station and is now a gliding centre — but the original 1940s station buildings, including the watch office and technical site structures, remain in various states of atmospheric dereliction alongside the active gliding operations. The combination of the accessible rural location, the WWII building heritage and the distinctive experience of derelict 1940s RAF architecture alongside an active airfield makes Lasham a uniquely layered Hampshire urbex destination.

4. New Forest Edwardian Sanatorium – 1900s-1910s Tuberculosis Pavilion Wards, Open-Air Sleeping Galleries Still Standing, New Forest Woodland Setting (Our Map Exclusive)
An Edwardian tuberculosis sanatorium in the New Forest — the original pavilion ward buildings with their characteristic open-air sleeping galleries still standing in the surrounding woodland, where patients slept in the fresh forest air as part of their treatment. Hampshire's dry climate and the New Forest's isolation made it an ideal sanatorium location; several were built between 1900 and 1920. GPS coordinates available with our England Urbex Map.
5. Hampshire WWII Anti-Aircraft Battery – 1940s Heavy AA Emplacement, Gun Platforms and Crew Bunkers, Solent Shoreline (Hidden Gem — Our Map Only)
A 1940s Heavy Anti-Aircraft battery on the Solent shoreline — the original gun platform circles still visible above the coastal grassland, the crew shelter bunkers and the command post infrastructure intact. The Solent shore was defended by dozens of HAA batteries protecting Portsmouth and Southampton from German air attack; the coastal grassland and saltmarsh environment preserves the concrete infrastructure extraordinarily well. Find it on our map — with access rating and condition report.
❓ FAQ
What is the most famous abandoned place in Hampshire?
Royal Hospital Haslar at Gosport — the oldest purpose-built Naval hospital in Britain, opened in 1753 and closed in 2009 after 256 years of continuous service. The Grade II* listed Georgian complex has been in progressive dereliction since closure.
What was Westbury House?
A Palladian-style Georgian country house near Bishop's Waltham — rebuilt after a 1904 fire, serving as a preparatory school and later a care home before being closed and abandoned. Documented on 28DaysLater as one of the most atmospherically complete derelict country houses in Hampshire.
Why does Hampshire have so many abandoned military sites?
Hampshire's strategic position — controlling the Solent approaches to Portsmouth and Southampton — made it the most intensively fortified county in England from Tudor times onwards. Every century from the 16th to the 20th added military infrastructure; when successive generations of defence technology made earlier works obsolete, the superseded structures were simply abandoned.
Safety Tips
- Asbestos: endemic in pre-1980 Hampshire military and institutional buildings — FFP2 mask mandatory in any enclosed space at Haslar or Lasham
- Tidal saltmarsh: Solent HAA battery sites can be cut off by tide — always check tidal conditions before visiting any coastal site
- Never explore alone — always bring at least one other person
The urbex code: "Respect the decay. It tells the story."
