La Casa Alvarado, Adobe residence in Pomona, California.

La Casa Alvarado is a single-story adobe house on Old Settlers Lane in Pomona, California, built in 1840. Of its 14 rooms, five belong to the original adobe; the rest are redwood frame additions made before 1900. Its sala measures 18 by 42 feet (5.5 by 13 m).

Built in 1840 by Ygnacio Alvarado on land provided by his friend Ygnacio Palomares, this adobe home was constructed during California's Mexican period. The building was added to the National Register of Historic Places in 1978 to protect its role in the region's early development.

The 18-by-42-foot sala doubled as a chapel for 45 years, used for services whenever padres came from Mission San Gabriel Arcángel; Palomares had granted the land on condition that Alvarado build such a chapel in his home. The room later held the Pomona Valley's first public school classes from 1870 or 1871.

The property remains a private residence with no public access to its interior spaces. Visitors can view the adobe structure and its architectural details from the street and surrounding area, gaining an appreciation for how homes were built during California's early period.

Starting in the 1870s, the main room housed the region's first public school classes, making it a center for early education in Pomona Valley. This educational use demonstrates how important the space became to the community's growth and development.
