The Galleria Nazionale d'Arte Antica (GNAA), or National Gallery of Ancient Art, is the main national collection of older (broadly, pre-1800) paintings in Rome. It has two sites: the Palazzo Barberini and the Palazzo Corsini.
The Palazzo Barberini was designed for Pope Urban VIII, a member of the Barberini family, by 16th century Italian architect Carlo Maderno on the old location of Villa Sforza. Its central salon ceiling was decorated by Pietro da Cortona with the visual panegyric of the Allegory of Divine Providence and Barberini Power to glorify the papal Barberini family.
The Palazzo Corsini, formerly known as Palazzo Riario, is a 15th-century palace that was rebuilt in the 18th century by architect Ferdinando Fuga for Cardinal Neri Maria Corsini. For a partial list of artworks, see Palazzo Corsini entry.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
