“Prvi Tumbin” refers to an overpass of the former Rovinj–Kanfanar railway line, constructed in 1876 and operational until 1966. This railway was a significant infrastructure project during the Austro-Hungarian Empire, connecting Rovinj to the broader European rail network. The overpass, located near the Mondelaco quarry, is a notable landmark along the “Staza Bazilica” trail, which traces the old railway route. The area is rich in history and natural beauty, making it a popular spot for hiking and exploration.
