One of the city's most famous buildings, this Catholic basilica still celebrates mass at 6pm daily, despite its dwindling flock. Its striking neo-Byzantine architecture and freshly restored more-is-more interior are matched by amazing views out to sea and across the capital. The basilica is on a hilltop at the eastern edge of the city and would be a long walk from the city centre. A taxi is around Dh400.
