Casa de López was a historical adobe building in San Diego, California, constructed in the early 1800s.

Often called la casa larga, or long house, it was built for the López family, early Spanish settlers of San Diego.

Walls were painted with a lime-based whitewash, inside and out, and interior floors were originally made of earth and pine-boards.

The population of Old Town was a mix of Mexican residents, indigenous Kumeyaay people, Hawaiian islanders, and a few American and European settlers.

[3] The American occupation of San Diego led to bitter divisions among residents who supported U.S. military rule and those who remained loyal to the Mexican government.

[8] The 1910 restoration of nearby Casa de Estudillo by architect Hazel Wood Waterman led to the gradual revival of Old Town.

The outbreak of World War II, however, led to its requisition by the U.S. Army which converted the casa and its courtyard into an anti-aircraft emplacement to defend Consolidated Vultee Aircraft Corp.

[14][15] By 1952, the casa’s condition had become so bad that the San Diego City Council voted to condemn and demolish the structure unless it was restored.

C. Arnholt Smith, president and chairman of the U.S. National Bank, and banker Douglas R. Giddings helped Fisher to form a nonprofit corporation to restore the building.

Architect Russell Rex added two new wings for a kitchen, dining room, and cantina, forming a U-shaped restaurant with a canopy-covered courtyard.

[4] Casa de López, with a current address of 3890 Twiggs Street, is now a restaurant in Old Town, San Diego.
