The Basilica of Sts. Vitalis, Valeris, Gervase and Protase is commonly named Basilica di San Vitale. It was built in 400 with funds provided by Vestina, a wealthy dowager, and was consecrated by Pope Innocent I in 401/402. The dedication to St. Vitalis and his family (Saint Valeria, his wife, and Sts. Gervasius and Protasius, their sons) is dated to 412.
San Vitale was restored several times, the most important being the rebuilding by Pope Sixtus IV before the Jubilee of 1475, and then in 1598, 1938 and 1960. The church is currently located several metres under the level of the street (via Nazionale), that it faces.
The portico is the most ancient part of the church, possibly dating back to the 5th century. It was altered at the end of the 16th century. The inscription on the portico, with the arms of Pope Sixtus IV, dates from this time. Pope Pius IX built the staircase to the 5th century portico in 1859.
The church has a single nave, with walls frescoed with scenes of martyrdom, among which a Martyrdom of St Ignatius of Antioch, in which a ruined Colosseum is depicted. The apsis, original of the 5th century, is decorated with a fresco by Andrea Commodi, The Ascent to Calvary.References:
The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
