The castle of Beselare, where the Van der Woestine family lived for 400 years, was located between the Keiberg and the Kortrijkdreve.
The decline began in the second half of the 18th century. Seized by a display of exaggerated splendor and wastefulness, Marquis François III Maximiliaan Antoon Van der Woestine began to sell homesteads, estates and forests around 1770. The wealthy bailiwick family Duval from Beselare was usually the buyer. The horrors of the French revolution did the rest. The hunt for the nobles was on and the marquis fell into the hands of the French and was beheaded on May 12, 1794 on the scaffold at Cambrai, together with other nobles.
His son and successor Charles Ghislain Van der Woestine became the last lord and margrave of Beselare. The French Revolution had abolished feudalism. The Marquis, also called the old Marquis or the Kwa Marquis, left the castle on September 7, 1796 and fled abroad. Many of the goods were publicly sold in 1802 and 1803 by the office of notaries Jan Baptiste Meersseman van Beselare and J. Vandermeersch van Ypres. A few years later, the plundered castle was also sold and shortly afterwards (around 1813) demolished.
There are still two copper engravings of the former glorious castle, one by J. Milheuser from 1641 and one by an unknown artist.
They are located in the convent of the Sisters of Mary in Izegem.
