The parish church of St Eulalia was built by the Aragonese towards the end of the 14th century and named after the patron saint of Barcelona. The building was severely damaged during WWII bombings. Restoration works have brought back the inside to its Aragonese-Gothic style. During the consolidation of the foundations of the building, archaeologists unveiled the remains of water cisterns dating back to the pre-Roman period, paved roads, a house and what was possibly a temple. The visit to the underground site gives an idea of how the various civilizations used the site for over 2,000 years, with the knowledgeable museum guides bringing the visitors deep down into the roots of the city. For those of you who don't speak Italian, captions are available in English, Spanish and French. Upstairs is the Treasure Museum, with an interesting collection of church paraments, chalices and statues.
