Smari has a very long history and was inhabited, according to reliable sources, from the proto-Minoan period onwards. The archeological relics in the Akropolis of the hill called Profitis Elias, excavated under the direction of the Archeologist D. Hatzi Vallianou, indicate a continuous human presence from the Middle-Minoan period to about 630 B.C.

The Palace of Malia, which covered an area of 7,500 sq.m. , was the third- largest of the Minoan Palaces and is considered the most "provincial" from the architectural point of view. The first Palace was built in 1900 BC and destroyed in 1700 BC when a new Palace was built. Following the fate of the other palaces in Crete it was also destroyed in 1450 BC. and the present ruins are mainly those of the new palace.

The Minoan villa at Vathypetro was most likely the residence of a local ruler. Its architecture is comparable to that of a "Little Palace": it has a central and west court, a small tripartite shrine, a three-columned portico, storerooms and workshops. It seems that the construction of the building was never completed. Interesting elements of its architecture are the installations of a wine-press in the south wing and an oil-press in the courtyard.
