The current Cathedral, the first example of Renaissance architecture in Turin, was built by order of Bishop Domenico della Rovere on the site of three medieval churches dedicated to the Savior, St. John the Baptist and St. Mary. The project, entrusted to the Tuscan architect Meo del Caprina, was carried out between 1491 and 1498. In the 17th century the building was renovated with the addition of the chapel of the Holy Shroud by Guarino Guarini, which connects the cathedral to the Royal Palace.
The bell tower of Sant’Andrea, completed in 1469, was raised in 1720 based on a design by Filippo Juvarra. The façade, with three elegant portals, with its white marble cladding was an anomaly compared to contemporary brick buildings.
The interior, with a basilica plan, is a Latin cross with three naves with Gothic elements. The side chapels house devotional altars; at the second altar of the right nave, polyptych of the Compagnia dei Calzolai by Martino Spanzotti and Defendente Ferrari.
The lateral stairs at the end of the presbytery lead to the chapel of the Holy Shroud. Built between 1668 and 1694 and designed by Guarino Guarini, it is a masterpiece of Baroque architecture.
