The castle is on a promontory in the center of the city, it was a Phoenician enclave and as a Roman fort it was key in the emirate with one abderraman entry. It participated in the riots of Ib Ben Hasun. The structure today is a little changed, it has a watchtower and moat and the best views. It can be visited every day except Monday and Sunday afternoons.
Crowning the Salobreña Albaycin is 10th century Moorish castle which adds a medieval charm to the Albaycin and offers some of the most spectacular views to be had in Salobreña. I'd recommend heading up there just before sunset to see the castle contrast with the pinks and purples of the sky and enjoy the dun dipping behind the Mediterranean cliffs. Not to be missed!
