Photo: Lost Crusaders' Tunnels Found Near Palace on Malta



Discovered in February 2009 in the capital of the Mediterranean island nation of Malta, this tunnel is thought to be part of a centuries-old underground water system built by the Knights of Malta.

Established in the 11th century, the military order was a key fighting force in the Crusades, a series of Christian military campaigns that originally had the goal of capturing Jerusalem. The Knights of Malta ruled the island from 1530 to 1798.
