Essex sits at the eastern gateway to London — a county of Thames estuary fortifications, Cold War secret bunkers and the post-industrial Thames corridor whose abandoned warehouses and power stations define one of the most distinctive urbex landscapes in southern England. Here are 5 of the best abandoned places in Essex, selected from our Abandoned Places Map UK — 640+ GPS locations across England, Scotland, Wales and Ireland.
Why Essex Is a Hidden Gem for Urban Exploration
Essex's urbex landscape combines three centuries of Thames estuary defence infrastructure, the extraordinary Cold War secret government bunker at Kelvedon Hatch and the post-industrial Thames corridor whose abandoned industrial buildings stretch from Tilbury to the sea. The county's proximity to London generates high search interest while its rural hinterland contains country houses and farmsteads that have been quietly decaying for decades.
1. Coalhouse Fort – East Tilbury, Essex — 1861 Thames Estuary Defence Fort, Napoleon III Threat, Used in Both World Wars, Heritage Site Open to the Public (Known Location)
Coalhouse Fort at East Tilbury was built in 1861 to defend the Thames estuary against the threat of French naval attack under Napoleon III — a polygonal earthwork fort with brick casemates for heavy guns covering the river approach to London. Used in both World Wars for anti-aircraft and coastal defence roles, the fort was finally decommissioned after WWII. The thick stone walls, the empty gun locations, the underground magazines and the dark brick casemate tunnels create an extraordinarily atmospheric military heritage site. Now managed as a heritage attraction, many areas retain the atmosphere of genuine abandonment.

2. Kelvedon Hatch Secret Nuclear Bunker – Brentwood, Essex — Cold War ROTOR Bunker, 3 Storeys Underground, Built to House Government During Nuclear War, Now Open to the Public (Known Location)
The Kelvedon Hatch Secret Nuclear Bunker is one of the most extraordinary Cold War sites in Britain — a three-storey underground facility built in 1952-1953 as part of the ROTOR radar network, later redesignated as a Regional Government Headquarters capable of housing 600 government and military personnel during a nuclear war. The bunker descends 30 metres below the Essex countryside; the operations rooms, dormitories, BBC studio and government chambers are preserved exactly as they were left when the Cold War ended. One of the most historically significant and most atmospherically complete Cold War abandoned places in England.

3. Abandoned Thames Estuary Grain Terminal – 1950s-1970s Bulk Grain Handling Complex, Concrete Elevator Silos and Conveyor Gantries Still Standing Above the River, Essex Shore (Exclusively on Our Map)
A 1950s-1970s bulk grain terminal on the Essex Thames shore — the original concrete elevator silos rising above the river bank, the overhead conveyor gantry system linking the silos to the ship loading berths and the control building with period equipment still in place. Essex's Thames shore handled grain imports from North America and Australia for decades; when bulk handling consolidated into fewer larger terminals, smaller operations were progressively decommissioned and left in place. One of the most dramatically scaled and most visually extraordinary abandoned industrial places in Essex. Discover its exact location on our England Urbex Map.
4. Abandoned Essex Victorian Asylum – 1850s-1870s Kirkbride Campus, Gothic Tower Still Visible Across the Essex Countryside, Chapel with Stained Glass and Airing Courts Intact (Exclusively on Our Map)
An 1850s-1870s Kirkbride-plan psychiatric asylum in Essex — the Gothic administrative tower still visible for miles across the flat Essex countryside, the chapel retaining original stained glass windows and timber pews and the enclosed airing courts where patients walked year-round. The bat-wing ward extensions and self-sustaining farm campus complete a Victorian institutional landscape closed by deinstitutionalisation and left in progressive atmospheric decay. One of the most architecturally extraordinary and most historically significant abandoned asylums accessible from Essex. GPS coordinates available with our England Urbex Map.
5. Abandoned Essex Georgian Farmhouse – 18th-Century Essex Weatherboard Farmstead, Original Timber-Frame Construction, Barn and Cart Lodge Still Standing, Rural North Essex (Exclusively on Our Map)
An 18th-century Essex weatherboard farmstead in rural North Essex — the original timber-frame farmhouse with its distinctive Essex weatherboard cladding still largely intact, the threshing barn with its pair of opposing cart doors and the cart lodge still standing in the farmyard. Essex's agricultural consolidation through the 20th century progressively emptied smaller farmsteads as larger holdings absorbed the land; the distinctive Essex weatherboard construction preserves them in the county's relatively dry climate. One of the most distinctively Essex and most architecturally characteristic abandoned places in the county. Included in our exclusive England map.
Safety Tips
- Thames tidal zone: the Essex Thames shore is tidal with unstable mudflat edges — never approach the riverbank without checking tidal conditions and never walk on Thames mud
- Asbestos: universal in pre-1980 Essex industrial and institutional buildings — always wear an FFP2 mask in any enclosed space
- Never explore alone — always bring at least one other person
The urbex code: "Take nothing but photographs, leave nothing but footprints."
