Le Roeulx has been one of the main residences of the Princes of Croÿ since 1429. It is one of the most imposing classical castle in the country. Its history overshadows that of all but the most prestigious residences in the Low Countries.
It opens one day a year for an international hot air balloon tournament. This year, that day is the 30th of June. Now if it rains on that day there will be no tournament and no rescheduling. We found that out last year but there will still be lots of food and drinks.
