The History Museum preserves a few Roman sites across the Gothic Quarter, such as the temple of Augustus and the Funeral Way on Plaça de la Vila de Madrid. But Plaça del Rei is where you can see Barcelona’s ancient history in detailed layers.
You’ll take a lift down to where the remnants of a garum factory, laundries, dyeing shops, and parts of ancient Barcino’s walls are all visible.
The site is large, covering 4,000 square meters, which you’ll explore via elevated walkways. As you rise through the museum building you’ll step forward through time and enter the vaults of the Palau Reial Major, the seat of the medieval Dukes of Barcelona.
