        ![]() as historic districts (areas that usually contain a number of 
buildings, structures, sites, and objects), each component of the 
district must be studied individually and evaluated as being 
either a contributing or a non-contributing factor in the 
district. 
There are also exceptions to the exceptions: 
o 
A religious property that derives its primary significance 
from architectural or artistic distinction or historic 
importance; 
o A building or structure that has been removed from its 
original location but is significant for architectural 
value or is the surviving structure associated with a 
historic person or event; 
o 
A birthplace or grave of a historic figure if there is no 
other appropriate site or building directly associated 
with his or her productive life; 
o A cemetery that derives its primary significance from 
graves of persons of transcendent importance, from 
distinctive design features, or from association with 
historic events; 
o A reconstructed building, when accurately executed as part 
of a restoration master plan, and when no other building 
or structure with the same association has survived; 
o 
A property, primarily commemorative, if design, age, 
tradition, or symbolic value has given it its own historic 
significance; and 
o A property that has achieved significance within the past 
50 years if it is of exceptional importance.  An example 
of an exception to the 50-year rule is the Dunes 
International Airport terminal, near Washington, D.C., 
constructed in 1962.  Designed by the architectural firm 
of Eero Saarinen and Associates, the terminal was 
considered to be of such outstanding architectural 
interest that it was declared eligible for listing on the 
Register in February 1978, only 16 years after it was 
built. 
Other, possibly less glamorous, exceptions that may be of 
special concern are the World War II "temporary" buildings 
constructed on military bases between 1939 and 1946.  A blanket 
demolition order was issued for these buildings by DOD in the 
early 1980s, but they are now protected by a special programmatic 
agreement (PA) .  By definition in the PA, World War II temporary 
buildings are those built between 1939 and 1946 and currently 
classified in the NAVFAC P-164 (see Section 2.6) as "T".  World 
War II buildings originally built as temporary, but no longer 
classified as such, are not covered by the PA.  The PA will
