Belfast is a city shaped by linen mills, shipyards and the Troubles — a Victorian industrial powerhouse that built the Titanic, the largest linen mill in the world and the legal infrastructure of a divided society. Its abandoned places carry all of that: a Victorian courthouse connected by tunnel to a gaol, a 1930s Art Deco dance hall in the zoo grounds and the extraordinary industrial heritage of a city that made ships for the world and then watched the industry disappear. Here are 5 of the best abandoned places in Belfast, selected from our Abandoned Places Map UK — 640+ GPS locations across England, Scotland, Wales and Ireland.
Why Belfast Is a Hidden Gem for Urban Exploration
Belfast's urbex landscape combines Victorian institutional and industrial heritage with the physical legacy of the Troubles — peace walls, derelict mills and the extraordinary shipyard infrastructure of Harland and Wolff that built the Titanic and Olympic. The compact geography of the city means extraordinary variety within a small area.
1. Crumlin Road Courthouse – Belfast — 19th-Century Victorian Courthouse, Connected to Crumlin Road Gaol by Underground Tunnel, Closed 1998, Decaying Grand Courtrooms (Known Location)
The Crumlin Road Courthouse was built in the 19th century as Belfast's primary judicial centre — a grand Victorian building facing the equally imposing Crumlin Road Gaol across the street, connected by an underground tunnel through which prisoners were walked from cell to dock without entering public space. Closed in 1998 after the courts were reorganised, the building's decaying Victorian courtrooms, empty judge's chambers and the underground tunnel to the gaol create one of the most atmospherically charged abandoned legal buildings in Britain. One of the most historically significant and most uniquely Belfast abandoned places in the city.

2. Floral Hall – Belfast Zoo, Belfast — 1930s Art Deco Dance Hall, Big Band Venue, Closed 1970s, Peeling Paint and Empty Dance Floor Above the City (Known Location)
The Floral Hall at Belfast Zoo was built in the 1930s as a glamorous dance hall and social venue — hosting big band performances for Belfast's dancing public through the WWII era and the post-war years. The Art Deco exterior, the sprung dance floor and the balcony overlooking the city were considered the height of Belfast nightlife. Closed in the 1970s and left to decay within the zoo grounds, the Floral Hall's faded Art Deco style, peeling paint and empty dance floor create one of the most nostalgically atmospheric abandoned places in Belfast.

3. Abandoned Belfast Linen Mill – 1870s-1890s Victorian Spinning Mill, Original Cast-Iron Columns and Overhead Shaft Drive System Still Intact, East Belfast (Exclusively on Our Map)
An 1870s-1890s linen spinning mill in East Belfast — the original multi-storey brick mill building with cast-iron structural columns, the overhead lineshaft drive system that transmitted power to every machine still mounted along the ceiling and the rope race holes in the floor where drive belts descended to the machinery below. Belfast was the linen capital of the world through the 19th century; when synthetic fabrics ended the linen trade, the mills closed progressively through the mid-20th century. One of the most industrially specific and most completely preserved abandoned linen mills in Belfast. Discover its exact location on our Ireland Urbex Map.
4. Abandoned Belfast Victorian Public Baths – 1890s Municipal Swimming Baths, Original Cast-Iron Gallery and Changing Cubicles Still Intact, Terrazzo Pool Surround, North Belfast (Exclusively on Our Map)
An 1890s Belfast Corporation swimming baths — the original cast-iron gallery still running around the pool hall perimeter above the changing cubicles, the terrazzo pool surround and the original ceramic tile wainscoting still lining the walls. Belfast built municipal baths as part of its Victorian public health programme; when modern leisure centres replaced them, several original baths were simply closed. One of the most unexpectedly beautiful and most architecturally rich abandoned places in North Belfast. GPS coordinates available with our Ireland Urbex Map.
5. Abandoned Belfast Edwardian Cinema – 1910s-1920s Picture Palace, Original Auditorium with Ornate Plasterwork and Balcony Still Intact, Period Projection Booth, South Belfast (Exclusively on Our Map)
A 1910s-1920s Edwardian picture palace in South Belfast — the original auditorium with its ornate plasterwork ceiling, decorative pilasters and curved balcony still largely intact and the period projection booth with original equipment above the stalls. Belfast's Edwardian cinema boom left the city with an extraordinary collection of purpose-built picture palaces; when multiplexes replaced them, several were simply locked and left to decay. One of the most atmospherically complete and most architecturally distinguished abandoned cinemas in Belfast. Included in our exclusive Ireland map.
Safety Tips
- Asbestos: universal in pre-1980 Belfast industrial and institutional buildings — always wear an FFP2 mask in any enclosed mill, baths or cinema space
- Structural instability: Belfast's older brick buildings have been subject to damp penetration over many decades — always assess walls and floors before entering
- Never explore alone — always bring at least one other person
The urbex code: "Take nothing but photographs, leave nothing but footprints."
❓ FAQ
What is the most famous abandoned place in Belfast?
The Crumlin Road Courthouse — a 19th-century Victorian courthouse connected to Crumlin Road Gaol by an underground tunnel, closed in 1998. The decaying courtrooms and the prisoner tunnel make it the most atmospherically charged abandoned legal building in Northern Ireland.
What was the Floral Hall?
A 1930s Art Deco dance hall built in the grounds of Belfast Zoo hosting big band performances through the WWII era and post-war years. Closed in the 1970s and left to decay within the zoo grounds; the sprung dance floor, balcony and Art Deco exterior are still largely intact.
Why was Belfast the linen capital of the world?
Belfast's damp climate was ideal for spinning linen yarn — the moisture prevented the fibres from breaking during spinning. Combined with the power of the River Lagan and cheap coal from Scotland, Belfast developed the world's most concentrated linen industry through the 19th century. At its peak the city's linen mills employed over 75,000 people.
