White’s cottage, built by Native Americans from the San Gabriel Mission in 1840 and known today as the Adobe House, is the oldest surviving structure in San Marino, California. Its mud-and-straw-packed walls have weathered the passage of nearly two centuries well enough, with scarcely a crack to be seen. What has changed is the view from the front porch. Modern suburbia has encroached on the house in such an unusual and drastic manner that city officials are considering moving the house to a different location altogether.
