Nakum is a large Mayan ruin located on the Holmul River north of Lake Yaxha. The first scientific explorer to visit Nakum was Count Maurice de Perigny (1877 - 1935) in 1905. Perigny mentioned Nakum in his 1908 report. Perigny returned to Nakum in 1909 spending six weeks clearing the site. The Peabody Expedition of 1909 visited the site from February 27, 1910 until March 21, 1910. Information gathered on this visit was used to produce the Peabody Museum Memoir, vol. 5, no. 3.
