Montegualandro Castle, Umbria, Italy. The walls date from the second half of the thirteen-hundreds. The first written record of the fortress’ existence dates to the year 917, confirming ownership by the Marquis Uguccione II. Later, Montegualandro was conquered by Frederick I Barbarossa, who turned it over to the Marquis Ranieri. Destroyed and taken by the Perugians in the mid-thirteenth century, the castle formed, from 1261 to 1476, part of the Montemelini estate.
