Written while the organisation he directs, Forensic Architecture, works to produce evidence for the International Court of Justice’s genocide case against Israel, in Ungrounding Eyal Weizman explores the larger geographical and historical context, from the displacement of the Nakba in 1948 to the present day. In unflinching and forensic detail, Ungrounding shows how architectural and territorial analysis is key to understanding the relationship between the coloniser and the colonised.It is an extraordinary and eye-opening journey through the ‘deep cartography’ of the area extending from Gaza’s subterranean tunnels through to its militarised topography, settlements and barriers. Territory is never a neutral backdrop nor the location within which a colonisation takes place. Instead, it is a mechanism by which colonisation is undertaken and key to understanding how Israel’s attack on Gaza in the wake of 7 October has escalated into violence so extreme as to, Weizman argues, meet the definition of genocide.
