The Cathedral of the Holy Cross and Saint Eulalia also known as Barcelona Cathedral, is the Gothic cathedral and seat of the Archbishop of Barcelona, Spain. The cathedral was constructed throughout the 13th to 15th centuries, with the principal work done in the 14th century. The cloister, which encloses the Well of the Geese (Font de les Oques) was completed about 1450. The neo-Gothic façade was constructed over the nondescript exterior that was common to Catalan churches in the 19th century. The roof is notable for its gargoyles, featuring a wide range of animals, both domestic and mythical.

The cathedral was constructed over the crypt of a former Visigothic chapel, dedicated to Saint James, which was the proprietary church of the Viscounts of Barcelona, one of whom, Mir Geribert, sold the site to Bishop Guislebert in 1058. Its site faced the Roman forum of Barcelona.
