# Eliza Document **Opening (not a real abstract):** (II) A r e all buildings that are constitutively surrounded by a particular outer physical context site-specific? Bacchini (2017): yes. I claim that things are more complicated than this (Caldarola 2021). (I) A r t y building has: (1) the property of being always located at a particular latitude and longitude; (2) the property of being always surrounded by a specific outer physical context. Bacchini (2017) asks whether (1) and (2) are constitutive or merely contingent properties of buildings. Bacchini argues that (1) is a contingent property of buildings. I concur. (Examples: the cathedral of Notre-Dame de Paris is relocated, along with the whole city of Paris, to Clark County, Nevada; the cathedral of Notre-Dame de Paris stays in the same place, and the city of Paris keeps changing its look throughout the years).
