Plain of Jars first site

The jars lie in clusters. The largest one near the town of Phonsavan, known as Site 1, contains over 250 jars of varying sizes. The jars now lie amidst thousands of unexploded bombs left behind by the Secret War in Laos in the 1960s. The large quantity of UXOs (unexploded ordnances), in particular cluster munitions, in the area means that only Sites 1, 2 and 3 are open to visitors - the others are considered too dangerous.
