Château D'Avin, located near Hannut in the wooded Avin valley, is a 16th-century château built upon foundations of a 14th-century medieval fortress. Situated within a landscaped park through which the Mehaigne River flows, the château features elegant facades, grand halls, and beautifully maintained gardens. Today it serves as a premier event venue accommodating weddings and corporate gatherings for up to 300 guests, with onsite accommodations including a gîte sleeping 22 people in 7 bedrooms, a Nordic bath, and modern amenities. The combination of historical architecture and contemporary event facilities makes it a distinctive heritage destination in the Walloon countryside.
