National Register Criteria
The National Register of Historic Places is the official list of the nation's cultural resources worthy of preservation. Properties listed in the Register include districts, sites, buildings, structures, and objects that are significant in American history, architecture, archaeology, engineering, and culture and which possess integrity of location, design, setting, materials, workmanship, feeling, and association. The National Register criteria for evaluating the significance of properties were developed to recognize all people who made a contribution to the country's history.

Cultural Resources are determined significant if they:
	A are associated with events that have made a significant contribution to the broad patterns of our history; B are associated with the lives of significant persons; C embody the distinctive characteristics of a type, period, or method of construction, or represent the work of a master; or possess high artistic values, or represent a significant concentration of resources whose individual components are united historically by function or plan; or D have yielded, or may be likely to yield, information important in prehistory or history.

Criteria Considerations
Ordinarily cemeteries, birthplaces, or graves of historical figures, properties owned by religious institutions or used for religious purposes, structures that have been moved from their original locations, reconstructed historical buildings, properties primarily commemorative in nature, and properties that have achieved significance within the past 50 years shall not be considered eligible for the National Register. However, such properties will qualify if they are integral parts of districts that do meet the criteria or if they fall within one of the following categories:
	A religious property deriving primary significance from architectural or artistic distinction or historical importance; or A building or structure removed from its original location but which is significant primarily for architectural value, or which is the surviving structure most importantly associated with a historic person or event; or A birthplace or grave of a historical figure of outstanding importance if there is no appropriate site or building directly associated with his/her productive life; or A cemetery that derives its primary significance from graves of persons of transcendent importance, from age, from distinctive design features, or from association with historic events; or A reconstructed building, when accurately executed in a suitable environment and presented in a dignified manner as part of a restoration master plan, and when no other building or structure with the same association has survived; or A property primarily commemorative in intent if design, age, tradition, or symbolic value has invested it with its own exceptional significance; or A property achieving significance within the past 50 years if it is of exceptional significance.
