Gorizia's Galleria Bombi: a 19th-century pedestrian tunnel reimagined as a digital art gallery
In the small north-eastern Italian border city of Gorizia, a pedestrian tunnel known as the Galleria Bombi runs beneath the city's castle and serves as a quiet bearer of the city's long, layered history. Newly added to Atlas Obscura's listings, the pedestrian tunnel was conceptualised in the mid-19th century, began to be dug in 1943, and opened in 1950; it is today a cultural venue hosting digital art exhibitions. Atlas's listing reveals the urban-historical framework behind the tunnel's apparently modest past.
Gorizia has historically lain within the borders of the Austro-Hungarian Empire. The town's development in the late 19th century was shaped by Italian unification (the Risorgimento) and by border politics. The original purpose of the Galleria Bombi was to provide a pedestrian connection between the city centre on the west side of the castle and the animal market (no longer existing, now in the Slovenian-side Rafut neighbourhood) on the east side. This type of underground link was a common method in European cities of the period for resolving urban circulation with limited infrastructure resources.
The tunnel takes its name from the local politician Giorgio Bombi. According to Atlas Obscura's account, Bombi played an important role in conceptualising the tunnel project and in securing its financing. The tunnel's official opening in the early 1950s was, after years of waiting, marked into the city's infrastructure memory as a sign of hope. At that period, Gorizia was in a reconstruction phase after the Second World War.
An interesting historical detail is that the tunnel's construction began in 1943. This date is the middle of the Second World War, and Gorizia's strategic position meant the city was under continuous threat of warfare. According to Atlas's listing, soon after digging started, the war interrupted the tunnel's purpose-built use; the reason was that local residents began using the tunnel not for urban transport but as a shelter against air raids.
From the perspective of urban infrastructure history, the Galleria Bombi's dual use is significant. Tunnels built in many medium-sized European cities became part of civil-defence infrastructure during the war years. In border cities like Gorizia, this role was especially important: the threat of air attack around the town caused infrastructure designed entirely for urban circulation to be dramatically transformed.
The tunnel's completion was achieved after the war, in 1950. At the opening, the city's mayor described it as a 'symbol of binding together in place of war'. Since then the tunnel has served as a passage between the two-end neighbourhoods within Gorizia's urban fabric, though its daily use has reduced with the reconstruction of main roads and progressing urban modernisation.
In the 2010s, the city administration launched a programme to reassess the tunnel as a cultural venue. According to Atlas Obscura's account, projection equipment and exhibition zones were added to the Galleria as part of this programme. The Galleria Bombi today hosts digital art exhibitions and interactive narrative installations. Annual visitors reach approximately 25,000 and contribute to Gorizia's cultural tourism flow.
The current exhibitions include works that connect past and present. One exhibition historically reflects on the various uses the tunnel took on between 1943 and 1950 (construction site, air-raid shelter, urban passage). Another addresses the border experience between the two sides of Gorizia — the Italian side and the Slovenian side — through visual narratives. Slovenia's accession to the Schengen Area in 2007 had removed border controls.
Gorizia and the Slovenian town opposite it, Nova Gorica, were selected jointly as EU Capital of Culture for 2025; the selection was made within the framework of a joint thematic programme embracing both cities' shared history. The Galleria Bombi has a special place in that programme: Bombi, one of the tunnel's originators, had his political career begin in the Austro-Hungarian period, and some of the workers who took part in the tunnel's excavation lived in what is today Slovenian territory.
In its closing assessment, Atlas Obscura notes that the Galleria Bombi is an example of perhaps Gorizia's 'longest-graded urban infrastructure'. Combining 19th-century planning, World War shelter use, post-war reconstruction and modern cultural reuse in a single 350-metre tunnel is an example of how European urban history is read through hidden places. The tunnel runs from the entrance on Trgovska ulica in the city centre eastward, and entrance is free; the digital art exhibition programme can be followed on the municipality's culture website.
