Castle of Ooidonk Belgian chenille tapestry features the Castle of Ooidonk located on the Lys river. This is easily one of the most beautiful castles of Belgium. Originally built in the 13th -14th century, it is a reflection of the Flemish-Spanish style of architecture that gives this castle its distinctive "Danish cookie jar" like appearance. The family which owned the castle, the Montmorencys, sold the castle in 1595 after it was destroyed several times between 1491 and 1579. The new owner Maarten della Faille rebuilt the entire castle in the Flemish-Spanish style.
