Castell de Castellcir

Spain, Spain

---

Castell de Castellcir, also known as Castell de la Popa, is a 10th-century medieval fortress located on a dramatic rocky spur called La Popa in Castellcir, Moianès region of Catalonia, Spain, first documented in 1014 as a strategic defense for the nearby valley.

Built to protect against invasions during the Marca Hispánica frontier era, it features ruins of perimeter walls and towers adapted to the natural rock formation resembling a ship's stern, with remnants of the nearby Ermita de Sant Martí chapel overlooking the landscape.

Now a Cultural Asset of National Interest in ruins due to early 20th-century looting, the site offers hikers breathtaking panoramic views and historical significance tied to local lords and bandit legends like "en Roma."
