The Bella Union Hotel in Los Angeles, California, constructed in 1835, is California Historical Landmark No. 656. It was effectively the last capitol building of Mexican California under Governor Pio Pico, in 1845–47, and was a center of social and political life for decades. The hotel was located at N. Main Street, on the east side, a few doors north of Commercial Street, which then ran east–west between Arcadia and Temple. The hotel was later known as the Clarendon and then as the St. Charles.
