These 14th-century arches bear the façades of a veritable island of homes along Carrer Merceria, which runs from the steps of the cathedral to Baixada del Patriarca. All but the last arch are Gothic, and the pillars are set at an incline to offset the tendency of the houses to slope downward as they near the street. In the Middle Ages, the site was home to a farmers' market. Today, an antique fair is held along the street and in the neighbouring Pla de la Seu on Sunday mornings.
