This video documents two interventions in the Mapocho River 2016. The first is called Reconstitución (Reconstitution) and is a homage to the action by ACA in 1980 when, during the dictatorship, this Artist collective poured red ink into the Mapocho River in protest at the passing of the new constitution by the Dictator Pinochet that, among other changes, declared himself President. The action by ACA was that the symbolic spilt blood of those murdered or disappeared would run through the whole of metropolitan Santiago from east to west in the causeway of the Mapocho River on the eve of this change. My intervention is a 360 recording of that possible journey – the red band of the inflatable ring holding the 3 gopro cameras (120 degrees each) is visible throughout as a filter over the water. The second intervention is a counter bridge suspended under the Racalamac pedestrian bridge over the Mapocho River in Providencia, Santiago. The mirror bridge is made of 300 suspended construction plumb bobs, each with the inscription “La ciudad enferma es rescatable” (the sick city can be saved), a saying attributed to the main protagonist in the modernization of Santiago in the late 19th Century: Benjamín Vicuña Mackenna. The intervention materializes the space created by the bridge and the nature of the river it crosses that is made invisible through the canalization project.
