Third Sector 
The center of the third sector is to the east of the two previous sectors, and it is called the Al-Buss site, and it consists of a main street heading from east to west and connecting the city with its eastern suburb. This street was built in the Roman era, and was restored in the Byzantine era, in the middle of the isthmus established by Alexander the Great. Arcades surround both sides of this street, and it is crossed by a great triumphal arch with three entrances. On its southern side, a canal hangs over aqueducts that were intended to draw the waters of the Ras al-Ayn spring into the city. On both sides of the street, large tombs intertwine with funerary structures, marble, limestone and basalt coffins of various shapes, decorations and sculptures. The period of use of this cemetery lasted from the second century to the sixth century AD. To the south of the cemeteries, there is a horse chariot race track, some parts of which have been restored. The field is 480 meters long and could accommodate about 20,000 spectators
