Visit RADIUS and the Water Tower during Open Monument Day

During the weekend of 12 and 13 September, RADIUS will once again participate in Open Monument Day. On both days, the water tower can be visited without obligation and you can enjoy the mesmerising view of Delft and its surroundings from its roof. RADIUS—located in the pump house and underground water reservoir opposite the water tower—is open that weekend with the exhibitions THE EARTH IS THINKING ALL ALONG... and MIRIAM HILLAWI ABRAHAM: THE NIGHT THAT DREAMS—COSMOLOGIES OF SCALE. Both exhibitions can also be visited free of charge this weekend. You will find a terrace with bar in the garden of RADIUS during Open Monument Day.

Listen to the audio tour about the water tower here.
