[2] Ubaldesca was born in the Republic of Pisa from a modest family, she dedicated herself to charity helping the poor and sick since early years.

[3] For all 55 years of religious life, Ubaldesca practiced humility and charity in the monastery and in the "Spedale" of the city, serving the sick and injured.

The church of Santo Sepolcro, Pisa holds a bust-reliquary of St. Ubaldesca (15th century) with a pail which, according to the tradition, belonged to the saint.

The Regata Storica sull'Arno (Historic Regatta on the Arno) is held in May in her honor and re-enacts the centuries-old activity of the ferrymen, who transported sand, brick and wood from Calcinaia to the port of Livorno.
