This thesis will examine theories and methodologies regarding the balance of natural aesthetics and architectural conservation in the preservation of architectural remains. Ruins have been used as historic garden "follies" for centuries, this thesis will examine how practitioners have balanced the ecological needs of the gardens with the conservation and preservation of ruins. The primary case study used for this thesis will be the Gardens of Ninfa in the Province of Latina, Italy, where conservators and landscapers have worked to preserve the gardens of the noble Caetani family and the Roman and Medieval ruins contained within the gardens for centuries. This thesis will examine how they chose to treat, interpret, and display the ruins within the existing garden landscape. This thesis will also explore the consequences of this approach based on the backdrop of the established theoretical principles of John Ruskin and Eugène-Emmanuel Viollet-Le-Duc, as well as the prevailing Italian theories on restoration of ancient ruins as given by prominent Italian theoreticians. Also examined will be the demonstrated capability and discussion of biologically-based conservation methods used in ruins conservation practice. / 0 / SPK / specialcollections@tulane.edu
