Home to some truly exceptional heritage, Picardy Wallonia has some real treasures in store for you. The Medieval city of Tournai houses Belgium’s oldest belfry and a 12th century cathedral, a remarkable religious building on more than one account. They are both UNESCO World Heritage sites. Ath, home of giants, is famous for its Ducasse, a masterpiece of intangible heritage. Last but not least, the Our Lady with the Rose Hospital is one of Wallonia’s major heritage sites, and a candidate to become a UNESCO site. Unmissable sites.
