Catalan Museum of Archaeology

On Montjuïc, the Catalan Museum of Archaeology traces the region's past from prehistory through the Roman conquest of Iberia, with rotating temporary exhibitions — visitors mention a well-received one on Sardinia — supplementing the permanent galleries. A perfect culture score and 4.5-star rating from over 2,500 reviews reflect real depth, and a standout VR reconstruction of Roman Tarragona gives the Roman galleries an unusually immersive edge for a museum of this size.

At roughly 90 minutes, it needs a proper visit to do justice to the range of material on display, from glasswork to full excavated rooms. It's best suited to visitors with a genuine interest in ancient history rather than those wanting a quick Montjuïc stop.
