types of historic aids to navigation as a general rule do not qualify for the
National Register. These would be:
- aids less than
50 years of age;
- reconstructed aids to navigation;
- aids to navigation
moved from their original sites;
- and collections of artifacts from aids
to navigation, including large artifacts such as lenses, fog signal equipment,
and other parts of light stations removed from their setting. However, some of
these properties may qualify for National Register listing if they meet the following
Resources Less than 50 Years Old:
An aid to navigation achieving significance within the past fifty years can be
listed in the National Register if it is of exceptional significance. To qualify,
an aid to navigation must be associated with important but recent themes or developments
(such as World War II) which scholarly or professional research has recognized
as significant in the history of aids to navigation engineering, construction,
or operation. Aids to navigation potentially eligible under these circumstances
would include, for example, the first Texas Towers installed to replace lightships.
An aid to navigation must be compared with other aids of its type that have similar
associations and qualities to establish exceptional significance.
Reconstructions: In rare instances, reconstructions at a historic light
station can be contributing elements of a National Register property if:
- the reconstruction is based on scholarly analysis of graphic, written,
and archeological sources;
- the reconstruction is accurately executed,
using appropriate period materials and construction techniques; or
reconstruction is presented in a historically appropriate manner as an integral
part of restoring a group of properties such as a light station which together
constitute a historic district. Reconstructed aids to navigation must be part
of an overall restoration plan for the entire resource.
Reconstructed aids to navigation are not generally eligible for the National Register
because they are not authentic historic resources.
