This small patch of green opposite the Hortus Botanical Gardens offers plenty of benches and views of the nearby canal that marks one of its boundaries. One shady corner is also the unlikely resting place for the ashes of Dutch victims of the Holocaust covered by blue glass, which is deliberately fractured to represent the symbolic cracks in the peaceful sky that was forced to watch the atrocities committed on the ground below. You can’t miss the park, as it is guarded by two large sphinxes at the gate.
