With the city's population growth and urban expansion outside the walls at the turn of the 20th century, a new gateway was deemed necessary.

[2] The winning design by architects Cesare Chiodi and Giuseppe Merlo proposed a monumental three-arch gate in the classicism style of Giovanni Muzio and the Novecento group.

[4] The gate provides access from Via Gramsci, located outside the city walls, to Via Manin and Via Mazzini in the historic center, and vice versa.

It is reserved exclusively for pedestrians and authorized vehicles, serving as the only vehicle-accessible entry to the historic center, subject to permission.

The gate, matching the width of the roadway, features a broad, lowered archway that extends just below the level of the adjacent pedestrian walkway on the walls.
