Cincinnati Street Gas Lamps
Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
About 1,172 cast iron gas street lamps remain in use in Cincinnati's neighborhoods and in parts of Columbia and Sycamore Townships. Each post stands roughly eight feet tall, weighs 200 to 450 pounds, and carries a Boulevard-style fixture. Most posts are believed to have been made around 1895 by a range of foundries, producing patterns such as full ivy, half ivy, fluted tapered, and composite designs. Gas street lighting began in Cincinnati when City Council bought one hundred cast iron lamp posts in 1843, and the number of lamps peaked at 9,512 in 1892 before electric lighting reduced it. The Boulevard fixture, patterned in 1898, became standard in the city. Lamplighters gave way to timing devices from 1928, and since 1956 the lamps have burned around the clock. The district was recognized as an example of lighting technology and for the unusual number of lamps still operating, which give many streets a distinctive yellow glow beside older architecture.
Significance in brief: The nomination argues the lamps illustrate technology and invention applied to lighting urban streets. Cincinnati is described as unique for the large number and wide spread of its gas street lamps. The lamps also add to the streetscape and give older neighborhoods a sense of time and place.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
