A 6,000 year-old set of household gear, including crockery and two wood-fired ovens, has been found in the buried ruins of a prehistoric farmhouse in northern Greece, officials said Thursday.

A Culture Ministry statement said the discovery"provides invaluable, unique information" on late Neolithic domestic architecture and household organization."This is a very rare case where the remains have stayed undisturbed by farming or other external intervention for about 6,000 years," the ministry statement said."The household goods are in excellent condition."
