On Chronology of Building Gates in the South-Eastern District in Chersonesos Taurican
South-eastern gates are the unique monument of the defense construction of Hellenistic period in Tauric Chersonesos. The gates were uncovered by the excavations headed by K. K. Kostsiushko-Valiuzhinich in 1899. Different researchers dated them back to the period of the mid-4 <sup>th</sup> - 3 <sup>rd</sup> centuries BC. In the course of excavations in 2009 it was revealed that the foundation of the gates included fragments of defensive walls of the earlier period. The chronological indicator to determine the construction date of Chersonesos south-eastern gates can be similar construction techniques and types of masonry used in the walls of Chersonesos citadel dated to the 80s-70s of the 3 <sup>rd</sup> century BC.
