At the center is Mariano Vallejo's home, La Casa Grande. (The tower was actually lower.)  Just to the left of the tower are the Servant's Quarters.  To the right of La Casa Grande are the Soldier's Barracks. Further to the right is the Mission Chapel and at the far right is the larger Mission Church.  Of these, the Mission Church and La Casa Grande no longer exist.

Construction of La Casa Grande began in 1835 and the Vallejo family moved into their new home in 1837, although construction was not finished until 1840.  

After Joaquin died, Maria Carrillo moved her family North to Sonoma. She stayed with the Vallejos, probably at La Casa Grande, until her move to her land grant in about 1838.

The Vallejo family lived at La Casa Grande until they moved to Lachryma Montis in 1853.

La Casa Grande burned down in 1867.
