The western front of Mespelbrunn Castle, a moated castle in the town of Mespelbrunn, between Frankfurt and Würzburg, Germany. It dates to 1427, when the family who lived in that location began to build it as defense against brigands who lived in the nearby Spessart mountains. Only the round tower (center-right) remains from that time; the remainder was constructed in the mid-1500s.Photo: Rainer Lippert
