El Born Centre de Cultura i Memòria

"The Born neighborhood has a bit of an artistic reputation, so it's really no surprise that when it came time to remodel their market, they re-imagined it as a historic and cultural center. The new project was first unveiled in 2013, corresponding with the tricentennial of the Siege of Barcelona—a hugely important date to Catalans, as it represents the end of the War of Spanish Succession and the last time Catalonia was independent from Spain. The market itself is a historic structure, as it was the first Spanish market to be built in the iron-framed, French market style, but an excavation beneath the old floor reveals ruins that date back to medieval times. A permanent exhibition explores life in the city in the early 1700s, and is a great way to dip a toe into the city's complicated and fascinating history. You can also check their website for lectures, music performances, and temporary art exhibitions."

"Bypass the lines at the nearby Picasso museum and stop in at the El Born Cultural Center for a unique look at Catalan history. Enter the massive 19th century market hall to find the archeological remains of 16th century Barcelona. You can admire the vast excavation site for free or take in a guided tour, one of their exhibits or concerts, all highlighting Catalan’s distinct history and culture. Before leaving grab a coffee at its café abuzz with the local hipsters." - Gemma Askham
