On a spit over Muharraq's sea channel crouches 15th-century Arad Fort in pure Arab style: conical towers and a re-watered moat — restored in original materials (clay, gypsum, palm trunks) it stays honest, and its night lighting ranks among the island's loveliest scenes. Come before sunset and witness the transformation; its grounds host seasonal heritage festivals; minutes from Bahrain airport — the smart pre-flight outing for the short of time.
