Franklin Park Conservatory
Why it's listed
Franklin Park Conservatory is a rectangular building of glass, stone and steel set in a park of about 100 acres in Columbus, Ohio. The land was once the Franklin County fairgrounds, used from 1886 to 1894. A glass dome with a finial rises from the center of a mansard-like roof, and the west facade has a projecting section with small glass towers. The cornerstone is dated 1895, when the structure was re-erected in Columbus. It is known to have been shown at the 1893 Columbian Exposition in Chicago, but records of its purchase and transport were destroyed in a fire at the old city hall. A red brick addition on the east side houses the city parks division, and a growing house is attached. Inside are about 250 tropical and desert plants. In 1910 a Wright Model B airplane delivered a bolt of silk here, billed as the first air freight delivery. In 1926 circus animals wintered inside.
Significance in brief: The nomination cites the building's architecture and its unusual history: it was exhibited at the 1893 Chicago exposition and re-erected in Columbus in 1895. It was also the delivery point of the first air freight flight in the United States in 1910. Records of its purchase were lost when the old Columbus City Hall burned.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
