The Manunggul jar was one of the numerous jars found in a cave believed to be a burial site (Manunggul, was part of the archaeologically significant Tabon Cave Complex in Lipuun Point, Quezon, Palawan) that was discovered on March 1964 by Victor Decalan, Hans Kasten ... I have visited the manunggul jar numerous times since that April of 1995 at the Kaban ng Lahi room of the National Museum II—The Museum of the Filipino People (former Department of Finance Building).
