The city history museum: a lift drops you into about 4,000 m2 of excavated Roman Barcino streets, a laundry, fish-salting and wine-making workshops under the Gothic square.

Placa de Sant Felip Neri
Quiet square with Civil War shrapnel scars on the church wall; 10 min.
The purest Catalan Gothic church, built in only 54 years (1329-83) by the port's workers; the wide, bare nave and slim octagonal columns feel strikingly light.
