Unit
- Historic preservation: The practice of protecting and maintaining buildings, objects, and landscapes with historical significance. It balances cultural memory against modern development pressures, requiring practitioners to weigh competing values such as authenticity, utility, and community identity.
- Ethical frameworks: Three core principles guide preservation: minimal intervention (do as little as necessary), reversibility (allow future generations to undo changes), and compatibility (new work should harmonize without imitating). These principles prevent irreversible damage while respecting the original fabric.
- Authenticity: The degree to which a preserved structure retains its original materials, craftsmanship, and setting. The Venice Charter (1964) established authenticity as a central value, warning against excessive reconstruction that falsifies historical evidence.
- Value assessment: Preservation decisions require evaluating a property's historical, architectural, social, and archaeological significance. Planners use criteria such as association with important events, embodiment of distinctive characteristics, and potential to yield information about the past.
- Stakeholder involvement: Communities, owners, government agencies, and preservation professionals must collaborate. Conflicting interests between economic development and cultural protection necessitate transparent negotiation and inclusive planning processes.
- Documentation: Systematic recording of a building's existing conditions through measured drawings, photographs, and written descriptions provides a baseline for treatment decisions and historical research. Proper documentation ensures the structure's story is preserved for future study.
- Adaptive reuse: The strategy of adapting historic buildings for contemporary uses while retaining their character. This approach supports sustainability by reducing demolition waste and conserving embodied energy, as well as maintaining neighborhood continuity.
- Preservation vs. restoration: Preservation aims to maintain the existing form, integrity, and materials of a historic property. Restoration, however, involves accurately recovering the form and details of a particular period, often removing later additions. Each approach serves different goals.
- Maintenance and stewardship: Regular maintenance is the most cost effective preservation strategy. Preventive measures such as cleaning gutters, repairing roofs, controlling moisture, and monitoring pests can forestall major interventions. This approach extends the life of historic materials and reduces the need for extensive repairs, aligning with the minimal intervention ethic.
- Legal frameworks: Preservation is often supported by laws such as the National Historic Preservation Act of 1966 in the United States, which establishes a review process for federally funded projects affecting historic properties. Local ordinances may designate landmarks or historic districts, providing regulatory protection that prevents demolition or inappropriate alterations without approval.
- Cultural significance: Preservation extends beyond physical fabric to include intangible heritage values, such as traditions, stories, and community associations. The Burra Charter of 1979 introduced the concept of "place" encompassing both tangible and intangible aspects, encouraging a holistic approach that respects the entire cultural landscape and the meaning it holds for people.

Movement: The Venice Charter (1964)
The Venice Charter for the Conservation and Restoration of Monuments and Sites established international standards for preservation practice. It emphasized that historic monuments are the common heritage of all humanity and must be conserved with respect for their original material and authentic documentation.
Modern Application: Today, the Venice Charter underpins national preservation guidelines worldwide. It influences decisions on whether to reconstruct, restore, or simply stabilize a structure. Practitioners refer to its articles when debating interventions like anastylosis (reassembling existing but dismembered parts).
