Santa Maria del Mar

Santa Maria del Mar was built between 1329 and 1383, an extraordinarily fast pace for a Gothic cathedral-scale building, and according to local tradition it was funded and physically built not by nobility but by the dockworkers, merchants and stevedores of the medieval Ribera district (today El Born), who hauled the stone for its columns from Montjuïc quarry down to the construction site themselves — a story commemorated in the novel and TV series "Cathedral of the Sea." That collective, non-aristocratic origin is part of why locals still refer to it with real affection, distinct from the more official, bishop-commissioned Barcelona Cathedral across town.

Architecturally, it's often cited as the purest example of Catalan Gothic anywhere: the style favoured wide, uncluttered interior spaces over the soaring verticality and dense ornamentation of northern European Gothic, and Santa Maria del Mar delivers this in its most stripped-down form — octagonal columns spaced unusually far apart create one of the widest uninterrupted Gothic naves in Europe, flooded with light from a rose window and clerestory glass rather than heavy stone decoration.
