Sited at the eastern terminus of 42nd Street, across the water from the United Nations headquarters, this museum-memorial tower takes the 1989 Tiananmen Square massacre as its subject and duality as its architectural logic. A glulam–steel composite structure shifts vertically along the tower’s 65-metre height, timber dominating above and steel gradually asserting itself below, until the base meets the water. Motor-operated wood facade panels open and close against a stainless-steel mesh skin, producing constantly shifting conditions of visibility and concealment. Visitors choose between two circulation paths — direct or wandering — moving through floors dedicated to exposure, research, contemplation and resolution. The building doesn’t resolve the tensions it raises. That’s the point.
