Rijeka is Croatia's principal port — a city that passed through Venetian, Habsburg, Hungarian, Italian and Yugoslav hands, acquiring a specific Central European industrial identity entirely unlike the Dalmatian coast. The world's first torpedo was invented here in 1866 by Robert Whitehead, in a factory that went bankrupt in the 1990s; its launching ramp still stands, crumbling into the Adriatic. The Hartera paper factory — one of the largest in Europe in its 19th-century golden era, hidden in the canyon of the Rječina river — closed after the Yugoslav economic collapse and now stands as an extraordinary industrial ghost city. Discover the 5 best abandoned places in Rijeka, selected from our Croatia Urbex Map — 400+ verified GPS locations.
Why Rijeka Has Croatia's Richest Industrial Urbex Heritage
Rijeka's specific urbex quality comes from its identity as a working port city — Habsburg engineering, Italian-era industrial expansion and Yugoslav socialist production all left substantial physical residue. The Rječina river canyon behind the city adds a dramatic natural setting to the industrial dereliction unavailable in any other Croatian port.
1. Hartera Paper Factory (Tvornica Papira) – Rječina Canyon, Rijeka — Founded 1821, One of Europe's Largest Paper Factories, Hidden Ghost City in River Canyon, Closed Post-Yugoslav Era (Known Location)
The Hartera paper factory was one of the biggest in Europe in its golden times and is now completely abandoned — a hidden ghost city in the canyon of the river Rječina. Founded in 1821 by Andrija Ljudevit Adamić, the factory operated for more than 180 years through wars, floods, fires and economic crises. It successfully operated until the 1990s, when war and post-war conditions caused market loss and obsolete technology to close it permanently. The 66-building complex in the Rječina gorge — with its turbine halls, chapel and footbridges over the river — is one of Croatia's finest industrial dereliction sites.

2. Whitehead Torpedo Factory Launch Ramp – Western Rijeka Port — World's First Torpedo Factory 1875, Robert Whitehead & Giovanni Luppis, 1930s Launch Ramp, Crumbling into Adriatic (Known Location)
Rijeka, Croatia was where the first torpedoes were assembled and tested. Robert Whitehead, working off Giovanni Luppis's prototypes, created and launched the first successful torpedo in 1866; in 1875 the Institute became the R. Whitehead & Co. Torpedo Factory — the first torpedo factory in the world. For 100 years the factory produced more than 30 different models. The factory closed in 1966. The launch station from the 1930s now stands basically falling apart — a shell of its former self, its only visitors the occasional urban explorer or fisherman. Atlas Obscura calls it "a testimony to the technical inventiveness of Rijeka at a global level."

3. Derelict Habsburg-Era Port Warehouse – Rijeka Waterfront — 19th-Century Austrian Commercial Infrastructure, Brick Construction, Port Setting, Adriatic Backdrop
Rijeka's Habsburg-era port infrastructure — built from the 1870s as the Austro-Hungarian Empire developed the city as its principal Adriatic outlet — included a network of brick-built warehouse and customs buildings along the waterfront. Several peripheral Habsburg-era port buildings in the Rijeka delta zone stand in states of dereliction between active port operations and privatisation processes: brick arched construction, iron loading crane armatures and the specific Central European industrial port aesthetic facing the Kvarner gulf.

4. Abandoned Rječina Canyon Mill – Rječina River, Rijeka Hinterland — Pre-Industrial Water Mill, Stone Construction, Forest Canyon Setting, Adjacent to Hartera Factory (Exclusively on Our Map)
In the Rječina river canyon above and below the Hartera factory complex, the remnants of the older pre-industrial water mill infrastructure that preceded the factory era stand in various states of stone dereliction: the mill channel, the mill house walls and the turbine pit opening visible in the canyon rock face. Guided Rijeka tours combine the Hartera factory with the canyon mill remnants as a single 4km canyon walk. The combination of the industrial factory ruins and the earlier mill archaeology in the dramatic karst canyon creates a dereliction experience of unusual historical depth.

5. Derelict Italian-Era Villa – Sušak District, Rijeka — 1920s–40s Italian Period Residential, Rationalist or Eclectic Architecture, Hillside Above Port, Kvarner Views (Our Map Only)
The Sušak district of Rijeka — historically a separate municipality where the Italian-Croatian border ran through the city — retains several 1920s–40s Italian-era residential buildings in states of dereliction on the hillside above the port. The specific Italian rationalist architectural vocabulary of the inter-war period, combined with the hillside Kvarner views and the specific atmosphere of the Sušak district's contested identity (Italian-Croatian border 1920–1947), creates a villa dereliction experience of layered historical resonance.

Safety Tips
- Hartera canyon: the Rječina river can flood suddenly after rain — never enter the canyon factories during or after heavy rainfall
- Torpedo factory ramp: the launch ramp is described as "neglected to the point that it might eventually end up in the sea" — assess structural stability carefully before approaching the ramp edge
- Factory asbestos: Yugoslav-era factories in Rijeka may contain asbestos insulation — carry an FFP2 mask for enclosed industrial spaces
- Never explore alone — always bring at least one other person and share your location
❓ FAQ
What is the most famous abandoned place in Rijeka?
The Hartera paper factory (Tvornica Papira) in the Rječina canyon — founded in 1821, one of Europe's largest paper factories, a ghost city of 66 buildings hidden in the river gorge. Closed after the 1990s Yugoslav economic collapse. Access from the Rječina canyon road south of central Rijeka.
Where was the torpedo invented?
In Rijeka — Robert Whitehead, working with Giovanni Luppis, created and tested the first successful torpedo here in 1866. The R. Whitehead & Co. Torpedo Factory produced over 20,000 torpedoes in 30+ models between 1866 and 1966. The 1930s launch ramp survives in a derelict state in the western port area, described by Atlas Obscura as a global industrial heritage landmark.
Is Rijeka good for urbex?
Exceptionally so — the Hartera factory and the torpedo launch ramp are two of the finest industrial derelict sites in Croatia, and Rijeka's Habsburg port infrastructure and Italian-era Sušak district add architectural layers unavailable in the Dalmatian coast.
