ART, CULTURE, ENVIRONMENT
Most of the art work of Sigillo can be found in church buildings: the Church of Sant'Andrea was built on the remains of an older church and has a single Neo-Renaissance nave, the Church of Sant'Agostino was built between 1788 and 1791 by Swiss architect Giacomo Cantoni on the remains of what was once the Church of Santa Caterina, of which only the medieval crypt remains, the Church of Sant'Anna is near the cemetery and built along the Via Flaminia in the mid-1400s, and then there is the Church of the Augustinian Monks. The former Church of San Giuseppe is worthy of note for the important paintings it houses and the frescoed vaulted ceiling dating to the 1930s. The Palazzo Comunale is on the main piazza and was built in the XII century. Today it houses the city archives.
Worth a visit outside of town are the remains of a substantial Roman bridge known as the "Spiano" and the Church of Santa Maria Assunta (XIII century) at Villa Scirca, one of the three oldest in Sigillo and home to frescoes done by the painter Matteo da Gualdo (1484).
