From the Guidebook:
The Lugo Adobe, said to have
been built in the 1840s by Don Vicente Lugo, was one of
the very few two-story houses in the pueblo of Los Angeles.
In 1867, Lugo donated this house on the Plaza to St. Vincent's
School (forerunner of Loyola University). From the 1880s
until it was razed in 1951, the building was occupied
by the Chinese.
