Originally built for the grand Ibero-American Exposition of 1929, Seville’s ­flamboyant neo-Moorish Plaza de España has for nearly a ­century been one of the city’s major ­attractions, an ornate ­showcase for Spanish architecture and ­decorative tiling.

But the several thousand visitors from around the world who throng the plaza every day, on foot or in horse-drawn carriages, may soon have to pay for the privilege, with proceeds from a planned entry fee going towards its upkeep.
