This monograph discusses the role that ruins play in urban centers in
terms of their meaning, testimony, and value, and the opportunities they
provide. After an outline of historical and contemporary of approaches,
with a special analysis of British and Italian approaches, Elisa Pilia
puts forward a methodology for the investigation of the strategic values
of such artifacts, and ideas for their potential contribution to a
sustainable requalification of historic urban cores. The protocol is
tested on the historical center of Cagliari, a mid-sized port city on
the southern coast of the island of Sardinia, Italy, where the remains
left by aerial bombardment during the Second World War are still a
dramatic part of the controversial European debate on how to reuse
ruins.
