of the entire structure. The octagonal plan of the basilica of San Magno has a short transept that provides the church with a cross shape. On the corners of the latter there are also four small chapels. The bell tower The original bell tower that served the basilica was that of the ancient church of San Salvatore. Not having structural problems, he saved himself from demolition. This bell tower was extended in 1542, while in 1611 it was restructured and strengthened to allow the placement of the bells consecrated by Federico Borromeo, which were larger and heavier. In 1638 another work of strengthening of the tower was carried out. In the middle of the eighteenth century the ancient bell tower collapsed for two thirds, and then on December 2, 1752, work began on the construction of a new bell tower. As already mentioned, the remains of the old one were transformed into a chapel, which is still visible behind the bell tower of the Basilica of San Magno on the south side of the building, near a covered passage. The design of the new bell tower was the work of Bartolomeo Gazzone. The new bell tower was built with a brick structure that replaced the one in stones of the previous bell tower. The height exceeds 40 meters. Along the walls were provided with pilaster lesene. The parsonage On the right side of the basilica there was, until 1967, an ancient 16th century clergy house. This building was enlarged in the seventeenth century by order of Federico Borromeo, and again in the eighteenth century when the new bell tower was built. Already at the end of the nineteenth century part of the structure was demolished. The rest of the buildings, as already mentioned, were demolished in 1967 to allow the construction of the new parish center, which was inaugurated in 1972 by the Archbishop of Milan Giovanni Colombo. The new rectory was manufactured in a modern style. Artistic works The facade and the entrance doors Originally the facade and the other external walls of the basilica were not plastered and presented with exposed bricks. The appearance changed radically in 1914, when the graffiti plasters were made, which covered the terracotta walls that had characterized the basilica for centuries, giving it an "unfinished" appearance: these works were carried out several centuries after construction of the church because the architect who designed
