Silimna

On a conical hill called Agia Triada, above the village of Silimna in Arcadia, five kilometres west of Tripoli, lie the scant ruins of a castle whose story is almost entirely lost. The plateau at the summit measures a modest 15 by 28 metres, and the position commands both the mountain pass from the Tripoli plain to the Elissonas valley and sightlines to the castles at Trikorfa, Davia and Kokkinies. The only documentary mention is an entry as Silimo in the Venetian catalogue of Morea castles of 1467, where it is noted as destroyed, though the identification is not certain. The rough stonework, bonded with strong lime mortar and tile fragments, suggests a Byzantine or Frankish build, but a wall of massive blocks hints at ancient fortification, possibly an acropolis of an unidentified city. Surviving traces include a small eastern gate tower, a cistern, a northern tower a metre high, and foundations of a possible external tower at the hill's foot.
