The Leta-Leta Cave, located at Langen Island, El Nido, Palawan, is an important burial site under the Late Neolithic Period of the Philippines. Excavated in 1965 by Dr. Robert Fox, the cave has a collection of stone and shell artifacts, potteries and nephrite adzes and axes. Also, yielded in the cave are two unique and beautiful pieces of potteries. One was a stem cup with an egg-like body, a round flat base and a narrow lip at its mouth. The second one was a double-gourd vessel which is an anthropomorphic jar depicting facial features.
