The temple of Apollo Lykeios at Sikyon was first excavated in the 1920's and reported that a Hellenistic temple had been built on the foundations of an archaic predecessor. The temple appears to have had three building phases, of which the final temple built in Doric style of 6 x 18 columns is dated to 303 B.C. The Hellenistic temple's stylobate was placed directly on the foundation euthynteria without a intervening krepis. The cella, pronaos, and opisthonaos are unusually long, nearly the full length of the peripteral colonnade, unusual in that it mirrors the earlier 6th century Archaic structure who's foundations were below it. The unusually long and narrow inner temple structure is more typical of the Archaic date and style. Both structures are oriented on an East-West azimuth. The cella interior walls were decorated with support columns and were carried by stone blocks at regular intervals supported by a slightly raised bench above the floor's surface. The construction method is much like that of the temples at Corfu or Tegea with the double row of cella columns.
