Solidly drenched with water, built in Poederoijen (Gelderland), where the rivers Meuse and Waal meet each other, stands the medieval castle Loevestein. It owes its name to the founder, knight Dirk Loef van Horne, who built it in the second half of the 14th century. Loevestein fortress also served as a strategic part of the New Dutch Water Line (19th century), besides it was also used as a prison. The most significant prisoner was a famous lawyer Hugo Grotius, sentenced to life imprisonment, who in 1621 managed to escape in a wooden chest for books. Currently Loevestein serves as a museum of the Middle Ages. Pictures by Dorota Mazur.
