In 2014 Lavau gained national and international attention with the discovery of a royal tomb dating from the beginning of the 5th century. This was found in a burial ground that began to be used in the 14th century BCE. The deceased was buried on a chariot in a burial chamber within a burial mound. Grave goods including gold bracelets, a bronze cauldron and black-figure pottery made this discovery truly remarkable for archaeologists and made Lavau an incomparable historic site.
