As covered by a variety of local, regional and national media, on december 30th 2014 two youngsters were stuck atop of the 40 m high historical chimney which is part of our Delft-based office building. They had ascended the structure using the grips along the side, but the police prohibited them from coming down themselves again because of the danger. Eventually, the fire brigade used a crane to bring them back safely. An ambulance was waiting for them.
This footage on Youtube shows what an impressive view the teenagers had.
