McElroy Octagon House, Historic house in the United States of America
The McElroy Octagon House is an architectural rarity and a historic landmark in San Francisco.
Built in 1861 by William C. McElroy, this residence reflects the octagon house fad of the mid-1800s.
The building represents the uniqueness of San Francisco's cultural heritage and architectural diversity.
Currently, it serves as a museum highlighting 19th-century life and the history of octagonal houses.
It is one of the few remaining octagonal houses in the United States included in the National Register of Historic Places.
