The Casa de Lopez site is a California Historical Landmark No.

José Manuel Machado built a house, Casa de Stewart, for his daughter Rosa.

Rosa married Jack Stewart, a pilot boat operator from Maine.

In the 1930s and early 1940s, it was a rooming house, café, art studio, and souvenir shop.

Casa de Machado was acquired by California State Parks in 1968, who had it restored.
