Cathédrale Saint-Sauveur in Aix-en-Provence took nearly a thousand years to complete, and it shows. Construction began in the early 6th century and continued until the 15th century, leaving a building that wears its Roman, Gothic and Baroque influences rather openly, like architectural strata in a canyon wall.

Some of the original stonework came from a temple dedicated to Apollo, repurposed when the Romans converted to Christianity in 338 AD. The baptistry, with two columns salvaged from that pagan temple and an original Roman font, claims the distinction of being France's oldest and the oldest structure in Aix itself.

Inside, a sarcophagus supposedly holds St Mitre, the city's patron saint who died in 466 AD. When the archbishops relocated their seat here in 1338, their decision prompted Aix's three separate walled communities to demolish their internal barriers and unite.
