Jaciment del Born, Archaeological site beneath El Born Cultural Centre in Barcelona, Spain.

Jaciment del Born lies beneath the 1876 cast-iron and glass market hall of El Born in Barcelona's La Ribera district. It preserves over 8,000 m² of the medieval and early modern street grid, with houses, palaces, workshops and a stretch of the Rec Comtal canal, all cut by the 1716 demolition for the Ciutadella.

The neighborhood was demolished in 1714 after the Spanish War of Succession, and military fortifications were built over the ruins, which preserved everything below ground. Excavations only began in 2001, revealing this buried community for the first time in nearly 300 years.

The market hall above the site, built by architect Josep Fontserè i Mestre in a modernist iron-and-glass style, opened in 1876. Since 2013 the whole complex has operated as El Born Centre de Cultura i Memòria, combining the excavated streets with exhibitions and public activities.

The site is accessed through El Born Cultural Centre, which sits in the Old Town and is easily reached on foot or by public transport. The excavations span multiple levels underground, so allow time to explore the different areas and wear comfortable shoes for walking on uneven surfaces.

The Rec Comtal, an open canal about 85 metres long and 4 metres wide, crossed the excavated area and set the orientation of part of the buildings. Archaeologists also documented one of its bridges at the junction of Carrer dels Ventres and Carrer de na Rodés.
