Knossos is one of four Minoan palaces uncovered in the 1900s. Other palaces are located in Mallia, Phaistos and Zakro. They differ in size. It has been cogently argued that the central building at Gournia is a smaller scale palace, and a recently excavated structure just east of Siteia at Petras is evidently an even smaller one. Currently, excavations are going on in Chania in west Crete. This site may reveal an equally large-scale site.
Verdict: Plagiarized.
