Long before Spain became a modern nation, the Iberian Peninsula was home to some of Europe's most fascinating civilisations. Iberian tribes, Phoenicians, Greeks, Romans, Celts and early Christian communities all left behind remarkable archaeological treasures scattered across mountains, valleys and coastlines.

For outdoor travellers, Spain's ancient sites offer the perfect combination of history and adventure.

Many are surrounded by hiking trails, natural parks, rural landscapes and campsites, allowing visitors to experience archaeology as part of a wider journey through Spain's countryside.
