About the museum
The Museo e Tesoro del Duomo di Monza preserves the possessions of the Basilica of Saint John the Baptist, whose core goes back to the liturgical furnishings given by the Lombard queen Theodelinda, later enriched by Berengar I and the Visconti. The first known inventory dates from 1275; the most serious losses occurred in the Napoleonic era, when in 1796 the basilica had to hand over two thirds of its gold and half of its silver to be melted down, and some works, such as the Crown of Agilulf and the Evangeliary of Ariberto, never returned.
The museum was established in 1963 as the Museo Serpero in a hypogeal structure beneath the Chiostrino (small cloister) of the cathedral, devoted mainly to the vanished early medieval basilica. In 2007 the extension, the Sezione Gaiani, designed by Cini Boeri, was inaugurated over two underground levels: it houses evidence from 1300, the year the reconstruction of the present basilica began, and works from the 14th to the 20th century.
Among the most important pieces are the so-called Cross of Agilulf, the votive crown and the binding of the Evangeliary of Theodelinda, the Reliquary of the Tooth of Saint John and the Reliquary Cross of Berengar I, the Chalice of Gian Galeazzo Visconti, the Sapphire Cup, the 16th-century tapestries and six silver reliquary busts. The museum is managed by the Fondazione Gaiani.
