Humana Building

[citation needed] The 26-story structure is headquarters of the Humana Corporation, and was designed by the Driehaus Prize winner and New Classical architect Michael Graves.

[3] Each side of the building is designed slightly differently, up to a sloping pyramid style for the upper few floors.

The north facade's loggia is respectful of the older downtown architecture, being flush with the original Main Street storefronts.

The large, curved portion towards the top of the building is an open-air observation deck.

The outermost point of the circle has space for a few people at a time to be surrounded by glass, allowing for views of the Ohio River and Main Street.
