Dab in the heart of the Montseny Nature Park, near the town of El Brull, rests the imposing Ausetani stronghold of El Turó del Montgrós. The settlement's strategic location guaranteed command of the routes leading inland from the coast towards the Vic Plane.
The fortress was occupied between the Bronze Age and medieval period. The site maintains its 150m long perimeter wall, raised in the 4th century BC and destroyed around 200 BC amid clashes between the Iberian tribes and Roman forces, albeit within the context of the Second Punic War (218-201 BC) or the revolt subdued by Consul Marcus Porcius Cato in 195 BC. The wall represents the archaeological site's primary attraction.
El Turó de Montgrós forms part of the Archaeology Museum of Catalonia's Iberian Route.
