Most people find this tranquil little plaza because they want to dine at Cafè de L’Acadèmia, but in Roman times, Jews and Christians came here to trade. The 13th-century church on the plaza, the Basilica dels Sants Just i Pastor, honors two Roman boy martyrs. The Gothic church stands on the site of the original 4th-century Christian basilica in Barcin; glass openings in the floor allow you to glimpse remains of a previous Romanesque church that stood here, which was the seat of the archbishop until the city’s cathedral was constructed. Only one tower of two planned towers was built on the asymmetrical building; you can go to the top for awesome views of the Gothic Quarter. The interior is full of mysterious surprises, including several images of the damned burning in hell. The fountain in the plaza, said to be the city’s oldest water source, was carved of Montjuïc stone in 1367. Above its three pipes you’ll see an image of one-handed Sant Just, another of the royal shield, and a third of a shield showing a hawk catching a partridge.
