Túnel de Montgat, Railway tunnel in Montgat, Spain.
Túnel de Montgat is a railway tunnel that runs approximately 135 meters through the Turó de Montgat hill and carries dual tracks. The entrances display castle-like architectural features in an eclectic style.
British engineer Joseph Locke designed this first railway tunnel of the Iberian Peninsula in 1848 as part of the Barcelona-Mataró line. The structure marks the beginning of modern railway technology in the region.
The structure earned recognition as a Cultural Asset of Local Interest in 1997, reflecting its importance in Catalan railway heritage. This designation shows how much the region values its engineering history.
The tunnel sits along the N-II road and serves regular train service connecting coastal towns between Barcelona and Mataró. Visitors can view the structure from outside, but should note that train traffic remains active.
The south entrance was reconstructed after explosion damage during the Spanish Civil War, replacing the original castle design with concrete. This rebuilt section remains visible today and reflects the conflicts of that era.
