Irrigation workers in Peru have discovered at least 35 ancient tombs that are believed to be up to 1,000 years old while working to lay down piping in the coastal region of Lambayeque.

Archaeologists supervised excavation efforts at the site to recover the tombs' remains as well as pots and ceramic pieces found at the site that experts believe may have been a cemetery for the pre-hispanic Sican culture.

Lambayeque also hosts the Royal Tombs Museum of Sipán which holds artefacts and interpret the tombs of major discovery in 1987.
