The ceiling above the high altar inside the Neo-Byzantine Basilique Notre-Dame-de-la-Garde in Marseille

The ceiling under the cupola of Marseille’s Neo-Byzantine Basilique Notre-Dame-de-la-Garde. The ceiling and wall mosaics cover about 13,000 square feet and were made from 1886 to 1892 in Nîmes from tesserae imported from Venice. Each panel has nearly 10,000 mosaic blocks per ten square feet, which amounts to about 12 million small tile blocks measuring ⅛ to ¼ inches square. These mosaics are of an exceptional decorative complexity designed by renowned architects of the time.
