1, 2, 3, 4, 5... you’ll have to keep counting for a while to reach 47, the number of arches stretching out before you! You’re now standing at Las Bóvedas, built between 1792 and 1796. This seemingly endless structure is considered the last colonial construction within Cartagena’s fortified walls. Originally, it served as shelter for Spanish troops against explosive attacks and as storage for ammunition used to defend the city. Like much of this historic Colombian city, Las Bóvedas has undergone several transformations over the years. It was used as a military barracks during colonial times, then became a prison during the independence era, where unfortunate inmates often found themselves knee-deep in seawater at high tide. By the early 20th century, the building had fallen into disrepair, but a restoration campaign by the national government saved it from further decline. That was a wise move, as it’s now one of Cartagena’s most popular tourist attractions. Beneath the vaults, you’ll find numerous artisan shops and art galleries. Keep your eyes peeled—you might just find the perfect souvenir here!
