Roberto Adobe and Sunol/Splivalo House located at 770 Lincoln Avenue in the Willow Glen area of San Jose, California. The adobe is the small structure in the rear of the house. The Roberto Adobe was built in 1836 and was the home of Roberto Bellarmino, a Valley Indian. The Sunol/Splivalo House was built by successive owners as an expansion of the small adobe, with a portion of the first floor added in 1854 by Antonio Sunol and an expansion and second story added in 1875 by Captain Stefano Splivalo.
