The Huaca de la Luna is a monumental grouping found on the lower part of the west slope of Cerro Blanco, 3 miles from the town of Trujillo. lt extends for approximately 315 yards north-south by 210 yards east-west.

Its three imposing platforms of adobe and brick, situated in front of the Huaca del Sol, are joined by four squares placed at different levels. One of them includes an outcropping of rock which doubtless had some ceremonial significance.

Both the platforms and the squares are bounded by very thick, tall adobe walls. Of these, the surrounding wall that closes the south side of the grouping is outstanding and makes a great corridor 20 yards wide, which stretches east until meeting the base of Cerro Blanco, making a total length of 200 yards.
