The Collegiate Church of San Secondo is built directly above the crypt containing the remains of Saint Secundus, a Roman martyr and Asti's patron saint.
The square is the traditional site where the city's medieval administrative records were historically kept and proclaimed.
Many of the surrounding buildings retain medieval porticos and arched columns that once protected merchant stalls from the weather.
The piazza features a distinct stone floor design that highlights the proximity of the ancient Roman forum underlying the modern city street level.
San Secondo is celebrated annually on the first Tuesday of May, a local public holiday featuring a historical parade in the square.
Piazza San Secondo is the central historical square of Asti, serving as the civic and religious heart of the city since the medieval period. It takes its name from the Collegiate Church of San Secondo, a Gothic structure built over the burial site of the city's patron saint. The square is framed by historic buildings including the Palazzo Civico, the city's traditional town hall. During the annual Palio di Asti, the square acts as a focal point for historic celebrations and local festivities. The space preserves the layout of the old medieval market district. Architectural styles represented around the perimeter range from Romanesque foundations to subsequent Gothic and Renaissance modifications. It functions as a primary pedestrian gathering point for both residents and visitors exploring the city's historic center.
From the center of the piazza looking toward the facade of the Collegiate Church, capturing the church and the historic porticos in one frame.
Visit during the morning market hours to see the square in its traditional active role, though most shops close during midday.
Observe the facade of the Collegiate Church closely to identify the different layers of stone masonry from various restoration centuries.
Look for the medieval carved stone heraldry on the surrounding portico columns.
Do not mistake the modern commercial storefronts on the outskirts of Asti for the historic center; the square is located specifically within the medieval city walls.
The square remains open to the public daily, though interior access to the Collegiate Church may be restricted during ongoing liturgical services.
Maintain a respectful demeanor when near the church entrance; modest dress is expected if entering the religious interiors.
