Santa Maria Assunta, Atri
The vault is also covered with frescoes and is divided into four architectural sections, each of them showing a main scene with one Gospel writer and a Father of the Church, and, in the lower corners, two theological virtues. On the walls there are the stories of the lives of Joachim, Anne and Maria. In the left aisle there are fine 14th-century frescoes and a majestic organs with 6000 canes, the biggest in Abruzzo. The Baptysterium is signed by Paolo de Garviis and dated 1506. Inside there is also the chapel of the Dukes of Acquaviva, ordered by Isabella Piccolomini in 1503. The floor before the presbyterium is partly in crystal tiles to show the ancient black and white mosaic floor from a Roman bath of the second century AD.
