National Trust for Historic Preservation wants to ensure that
historic America is protected against destruction and negligence.
The not-for-profit organization was founded in 1949 and educates,
advocates, and provides resources for the preservation of historic
buildings and land (not to be confused with the National Register
of Historical Places, which designates buildings and
neighborhoods as historic). The group also
operates about 30 historic sites across the US. National
Trust, which boasts about 270,000 members, operates out
of a Washington, DC, headquarters and nine regional and
field offices. It also works with thousands of
preservation groups in all 50 states.
