It was built in 1928 by the architect Pietro Angelini under an ancient XV century arch which frames it. The source, built in medieval style, fits harmoniously into the context of the street, so much that it seems coeval, but the inscription in Roman characters refers to the XX century. In the central panel of the basin, as in other fountains and public buildings, the griffin, symbol of Perugia, is carved.
The name of the fountain and of the street refers to an 1297 anonymous Marian painting: "la Maestà", placed as a deterrent for criminals, under a dark vault of the ex-Palazzo del Podestà. In 1335, the Oratory of the Majesty of the Vaults was erected to protect the fresco. Destroyed by fire, the oratory was rebuilt in 1567 with the facade of Bino Sozi, which can still be seen today. The arch with pink and white stones belonged to the previous building. Inside, in addition to the repaint Majesty (currently no longer in place), decorations by Niccolò Circignani, called Pomarancio can be seen.
On the right of the oratory, there is a ceramic panel placed there at the end of the World War II by G. Belletti (1945) and made in the C.I.M.A workshops in Perugia. It represents the Madonna enthroned with the Child and the Saints Ercolano and Costanzo presenting the city to the Virgin.
