An unknown soldier whose treasure-laden tomb lay undisturbed for some 3,500 years was unearthed by US archaeologists in Greece.

Gold, silver and ivory objects and jewelry were among the finds recovered from the site of the Mycenaean-era Palace of Nestor on Greece's Peloponnese peninsula. Archeaologists Jack L. Davis and Sharon R. Stocker from the University of Cincinnati say that the quality and artistry of 1,400 found pieces suggest the influence of the Minoans on the later Mycenaean culture.

The treasure is said to be "the most important to have been discovered in 65 years" in continental Greece, the Greek culture ministry said.
