The excavations carried out beneath the Santa Caterina Market revealed the archaeological remains of the former Convent dels Predicadors in Barcelona (Convent of the Preachers), which was later renamed the Convent de Santa Caterina. Other religious buildings and a late-Roman necropolis were also unearthed, the latter containing amphora, tegulae and formae tombs (made with building materials). Part of the site has been preserved and is open to visitors. Plans are underway to create a visitor centre to provide key information about the site and its evolution from prehistoric times until it became a market.
