The castle of Kolossi, also known as Kulas, is one of the most important extant fortification works in Cyprus from the era of Frank domination. It is directly linked to important events of the history of Cyprus. The most important of these being the conquest of the island by Richard Coeur-de-lion and -later on -by the Knights Templar and by the Order of St. John of Jerusalem (Knights Hospitallers).The fortress of Kolossi, which reminds of a fairly large tower, was built in 1454 by the Grand Commander of the order of St. John of Jerusalem, Louis De Magnac, upon the ruins of an older fortress of the 13th century.
