Criteria for Designation of Historical Landmarks
The designation of a historical landmark is a prestigious recognition that acknowledges a site's historical, cultural, or architectural significance. This process involves a rigorous evaluation based on specific criteria that have been established to ensure the preservation of heritage sites. Various entities, from local city commissions to national bodies, have developed criteria to evaluate these landmarks.
National Historic Landmarks
In the United States, the National Historic Landmarks Program is administered by the National Park Service. A site can be designated as a National Historic Landmark (NHL) if it possesses national significance. The NHL designation relies on six primary criteria to assess this significance:
-
Association with Events: The site must be associated with events that have made a significant contribution to the broad patterns of American history.
-
Association with People: The site should be associated with the lives of persons significant in American culture.
-
Architectural Significance: The property must embody the distinctive characteristics of a type, period, or method of construction or represent the work of a master, possess high artistic values, or represent a significant and distinguishable entity whose components may lack individual distinction.
-
Potential to Yield Information: The site should have yielded, or may be likely to yield, information important in prehistory or history.
-
Integrity: The site must retain a high degree of integrity. This includes the physical features that convey its historic character.
-
Exceptional Value: If a property doesn't meet the first four criteria due to age or another reason, it must possess exceptional value or quality in illustrating or interpreting the heritage of the United States.
Exceptions
There are exceptions to these criteria. For example, properties owned by religious institutions or used for religious purposes may still be designated if they meet higher standards in other criteria.
Local and State Designations
Apart from national designations, local and state bodies have their own criteria for landmark designation. For instance, the New York City Landmarks Preservation Commission evaluates sites based on architectural, historical, and cultural significance within the city. Similarly, California Historical Landmarks must meet at least one of several defined criteria to be considered of statewide significance.
Example Criteria
-
Historical Significance: Sites such as those associated with significant events or persons at the state or local level.
-
Architectural Integrity: Buildings that are prime examples of architectural styles or the work of prominent architects.
-
Cultural Importance: Sites that hold cultural significance to a community, reflecting its traditions, beliefs, and values.
Preservation and Impact
Once a site is designated as a historical landmark, it gains protection under preservation laws, which can affect development and alterations. This recognition not only helps in conserving the architectural and historical integrity of a site but also promotes tourism and educational opportunities. Chicago, Dallas, and Baltimore are examples of cities that have their own landmark designation processes, reflecting a combination of historical, economic, and cultural values.
