Castell de Sant Martí Sarroca is a 10th-century castle perched atop La Roca hill in the Alt Penedès region of Barcelona province, with origins dating to 966 when Galí of the Santmartí family ordered its restoration. This medieval castle offers stunning views of the Montserrat mountains and commands views across the Penedès region from its hilltop position beside a historic church. Restored and now containing a museum, the castle welcomes visitors through guided tours available in multiple languages, making its rich medieval history accessible to those interested in Catalonian heritage and architecture.
