PHILIPPOPOLIS (Elena Kesyakova – RAM.Plovdiv@gmail.com) The archaeological excavations in the western propylaea of the forum were carried out in 2012 – 2015. In 2019, conservation, restoration and exposition of the site were carried out. A section of the stylobate with syenite bases, 30 m long, was documented. Three columns of the marble colonnade in the Roman Corinthian order were restored over the stylobate. The columns were 6.80 m high, while the entire order was 12.48 m high. The junction of cardo and decumanus and the platform of the western propylaea with staircases from the three sides were exposed. The western propylaea were the most important in the forum, according to a discovered marble altar with a Greek inscription that read: “To Heros, who protects the propylaea, I devote, Herakleitos”. A good visibility of the four construction periods of the forum was provided, featuring the platform of the propylaea with staircases from the three sides, the different pavements of the streets during the four construction periods, the drains of the cardo during the last two construction periods and the latrine. The early stylobate belonged to the first construction period. The construction of monumental propylaea belonged to the second construction period. The sandstone thresholds of the shops and the new pavement of the streets belonged to the third construction period. The marble colonnade in the Roman Corinthian order over the stylobate, the marble pavement of the area, the syenite thresholds of the shops and the second pavement of the streets belonged to the fourth construction period.
