The amazing medieval monuments, dramatic castles and fortresses of the Peloponnese can hardly be overstated. The fabulous Venetian, Frankish and Turkish castles of  Methoni and ancient Corinth; the strange battle towers and frescoed churches of the Mani; and the extraordinarily well-preserved Byzantine enclaves of Mystra and Monemvasia  compliment a striking natural landscape. Another breathtaking Peloponnese attraction is Palamidi Castle, a fortress with remarkable views that looms over the city of Nafplio.
