Lupukngna was a coastal Tongva village that was at least 3,000 years old located on the bluffs along the Santa Ana River in Huntington Beach near the Newland House Museum.
[7][8] The Diego Sepúlveda Adobe was built overlooking Lupukngna and Genga from between 1817-1823[9][10] as an outpost "to watch over cattle and Indians."
[7] In 1935, archaeologists found evidence of a village along the Santa Ana River near contemporary Adams Avenue.
Numerous Tongva villages in the area were established on other similar knolls, making the location more probable.
[12][13] A small residential street in Costa Mesa near the Diego Sepúlveda Adobe is named Lukup Lane in reference to the village.
