Abbaye Saint-Victor, Marseille
Tel: 33 4 96 11 22 60
Concierge.com's insider take:
On the south side of the port lies the Basilique St. Victor, a Romanesque basilica constructed in the fifth century by St. Cassien, and then destroyed by the Saracens; the fortified Gothic church was a later addition. The restored abbey is still used for worship, and the tomb of two martyrs, dated to A.D. 250, rests among the catacombs and sarcophagi.
Open daily from 9 a.m. to 7 p.m.
