The castle stands on the site of the ancient acropolis of Methymna, which dates back to the pre-Christian era.
The Genoese Gattilusio family extensively renovated the castle in 1373, leaving their distinct heraldic emblems on the walls.
Despite multiple sieges, the fortress was only successfully breached by the Ottoman Sultan Mehmed II in 1462.
The layout features a 'keep' or donjon, which was the final line of defense during an invasion.
The masonry incorporates repurposed ancient stone blocks from older temples in the surrounding area.
Archaeologists have identified subterranean cisterns used to store water during prolonged sieges.
Molyvos Castle sits atop a strategic hill overlooking the Aegean Sea on the northern coast of Lesvos. Its current structure dates primarily to the 14th century, built by the Genoese Gattilusio family over Byzantine foundations. The fortification features a double-walled defensive system and a prominent moat, reflecting the military architecture of the Byzantine era. The site historically protected the town of Mithimna from pirates and invading forces. Visitors can explore the internal courtyards, stone vaulted chambers, and the ramparts that offer views toward the Turkish coast. The castle served as a significant administrative and military hub under Ottoman rule following its capture in 1462. Archeological evidence suggests the site has been fortified since antiquity due to its elevated, command-of-view position. Today, it remains the most well-preserved fortress on the island of Lesvos.
