The Marian Sanctuary of Monte Grisa is a Catholic church located in the north of the city of Trieste, at an altitude of 330 meters on Mount Grisa, from where you can enjoy a spectacular view of the city and the gulf.
The sanctuary was designed by the engineer Antonio Guacci based on a sketch by the bishop of Trieste Antonio Santin. In fact, the bishop made a vow to the Madonna to save the city menaced during the Second World War and, as a sign of gratitude at the end of the war, he promoted the construction of this temple.
It was built between 1963 and 1965, and inaugurated by the same bishop on 22 May 1966.
The building consists of a triangular structure, reminiscent of the letter M (as a symbol of the Virgin Mary). The structure is entirely in reinforced concrete, which defines two big superimposed churches.
It is considered a classic example of brutalist architecture.
