Saint Ubaldo Day is still celebrated at the Basilica of Sant'Ubaldo in Gubbio in his honor, as well as at Jessup, Pennsylvania.

He learned that Peter de Honestis some years before had established a community of canons regular at the monastery of Santa Maria in Portofuori at Ravenna.

Ubald went there, where he remained for three months, to learn the details and the practice of their rules, wishing to introduce them among his own canons of Gubbio.

Peter opposed the notion as a dangerous temptation, and exhorted him to return to his former vocation, in which God had fixed him for the good of others.

The saint endeavoured to make it pass for an accident; but when that could not satisfy the people, who knew how it happened, he being desirous to deliver the man out of the hands of the magistrates, maintained that the cognizance of the misdemeanour belonging to his own court, he would take care to do himself justice.

Ubaldo became commander of the Gubbio forces, which saw an overwhelming victory, which the populace attributed to the miraculous intervention of its bishop.

In 1155, after the sack of nearby Spoleto He later met with Emperor Frederick Barbarossa, who subsequently spared the city from attack.

In 1194 it was moved to the small oratory on the top of Mount Ingino overlooking the city, where in 1508, at the wish of the Duke of Urbino, the Canons Regular of the Lateran had built a church.

Dante mentions Ubald in the Divine Comedy (Heaven Canto XI): “Between Tupino and the stream that falls down from the blest Ubaldo's chosen hill the slope is green a lofty mount below".

Outside of Italy, a finger relic of Ubald is venerated in the Saint-Theobald collegiate church of Thann, Haut-Rhin (France).

A celebration like the Corsa dei Ceri is held also in Jessup, Pennsylvania, where people carry out the same festivities as the residents of Gubbio do by "racing" the three statues through the streets during the Memorial Day weekend.
