Although largely rebuilt, Alcúdia's fine city walls are impressive. Those on the north side are largely the medieval originals while near the Porta Roja (Red Gate) are remnants of an 18th-century bridge. From the bridge, you can climb up and walk around 250m atop the walls, as far as Carrer del Progres, with fine views over town and towards the distant hills. Beyond the bridge to the northeast, the Plaça de Toros (bullring) has been built into a Renaissance-era fortified bastion.
