The McElroy Octagon House was built between 1860 and 1861 by William C. McElroy, a wood miller, on Gough Street in what is now the Cow Hollow neighborhood. Originally two floors of four rooms each around a central winding staircase, it survived the 1906 earthquake with damage and later stood vacant before being restored and opened to the public for tours.
