The Edwin Hubble House: From 1925 to 1953, this two-story stucco home was the residence of one of America's greatest 20th-century astronomers, Edwin Hubble, who, among other accomplishments, discovered extragalactic nebulae and their separation from each other.
Across from City Hall is the Centennial Clock, standing at the northeast corner of Huntington Drive and San Marino Avenue, donated to the community in 2005 by the Rotary Club of San Marino in celebration of Rotary International's 100th anniversary.
