John A. Rowland built it in 1855 on the La Puente Rancho.","why_significant":"The nomination calls it the oldest two-story brick house, and the oldest brick house still standing, in Los Angeles County. It was built with bricks from the newly formed Mulluly Brick Co. of Los Angeles. John Rowland and William Workman led the first American wagon train settlers into Southern California in 1841. The site also reflects a long sequence of land use, from Awig-na Indian settlement through mission, rancho, agricultural and suburban periods.","narrative":"Built in 1855 by John A. Rowland, this two-story brick house in the City of Industry area of Los Angeles County is described as the oldest two-story brick house, and the oldest brick house still standing, in the county. Its bricks came from the newly formed Mulluly Brick Co. of Los Angeles. The original plan was H-shaped, with solid brick walls 10 to 15 inches thick, five fireplaces, two travellers' rooms off the front porch and a wine cellar in the basement. Stucco, a changed roof line and a modern kitchen were added in 1897, and rooms were altered in 1920. An adobe cook house from Rowland's earlier 1842 adobe survives at the rear. Rowland and his partner William Workman led the first American wagon train settlers into Southern California, arriving in Los Angeles in November 1841, and later received the La Puente Rancho grant. The house is now a museum maintained by a local historical society.","period_of_significance":null,"architect_builder":"John Rowland, builder and owner; bricks from the J.
