The dominant tone of Corsica's most successful commercial town, BASTIA, is one of charismatic dereliction, as the city's industrial zone is spread onto the lowlands to the south, leaving the centre of town with plenty of aged charm. The old quarter, known as the Terra Vecchia, comprises a tightly packed network of haphazard streets, flamboyant Baroque churches and lofty tenements, their crumbling golden-grey walls set against a backdrop of maquis-covered hills. Terra Nova, the historic district on the opposite side of the old port, is a tidier area that's now Bastia's trendy quarter.
