MARSEILLE, France (AP) — Marseille, host of the 2024 Olympics sailing competition, is a city of contrasts. It’s a millennia-old port, crossroads of cultures and faiths, where the sea is ever present but not equally accessible, and the beauty and cosmopolitan flair rub shoulders with enclaves of poverty and exclusion. At the other end of its spectacular, monument-fringed bay from where the world’s best sailors are racing, inner city children learn to swim in the Mediterranean that many see from their homes, but have never dipped a toe in.
