Agia Mavra Castle
Built c.1300 by John I Orsini as a frontier fortress controlling access to Lefkada via its causeway, this castle is the most legible material trace of the Latin crusader lordship era on any Ionian island. Later modified by Ottomans (1572–74) and Venetians (1684), its layers encode three ruling powers in one structure. The castle's position at the Lefkada causeway makes it a network anchor — the gateway through which all land traffic passed.
