Looming over Argos, Larissa Castle is a crumbling conglomeration of purple-flower-studded towers, bastions and wall sections – contributed by Roman, Frankish, Venetian and Ottoman Turk conquerors – that stands on the foundations of the city’s principal ancient citadel. Much of the citadel is undergoing restoration, but the all-encompassing views from the top are well worth the ascent. Take Tsokri street west from the centre and follow the signposts to the narrow road that winds around the back of the ruined keep.
