The climber was also spotted high on the building at about 4:30 PM, reports Het Nieuwsblad.
“A heritage guard saw the man jump from battlement to battlement,” said Doreen Gaublomme, director of Historic Houses. “Before the police arrived, the man was able to get away. As he walked out of the gate, he shouted in English: Sorry for the problems”.
Witnesses were able to give a description of the climber to the police, but he remains unknown.
