The Archivo Histórico Dieciséis of Barcelona is located in a charming plaza in the heart of Barcelona. Many parish records have been centralized to this archive, so if you have ancestors in the city of Barcelona, this can be a great resource. Just tell the security guard you’re going to the archive, and he’ll let you in.
The archive itself is on the third floor. You can only order up to four documents per person per day, so plan accordingly. There are indexed copies of the records created by the Dioceses throughout the room, but keep an eye out for little black plaques located on the bottom- right of each drawer indicating that those records are actually held by the archive. Everything else was indexed before the civil war, and the original records were then destroyed during the war.
