As part of the Roman province of Lebanon, Byblos prospered and the city expanded and the city was said to be the summer destination for the roman Governors. Coins were minted in Byblos bearing the names of most of the Roman Emperors in that time. The most famous are the coins of Macrinus showing the famous temple of Astrate or Baalat Gebal.
Famous is the via romana built in the 2nd century BCE. An aqueduct brought more water to the ancient well and distribution network was built in the promontory of the archaeological site in Byblos , and if you look well you can still see embedded reservoirs in the earth and pipes coming in and coming out.
The roman amphitheater we see today has been displaced from it original location but though never been a large amphitheater
In the second century BCE, a nymphaeum was added, we can still see till today on the north-east of the site, and has some very fine sculpture . Water installations are abundant at that location.
Also on top of the hill of the promontory we can see Roman columns standing at the location of a previous Roman temple.
Another small roman temple can be found on the south-east where we can see the remains just walking after the Persian fortress.
Also on the north part of the site just at the right of the entrance we can see the remains of a large Roman Bath stretching for over 80m till the small house standing on the site on north of the north west of the site. Walking from the beginning just next to the entrance of the site we can see the caldarium and the trepidarium and water reservoir for the caldarium.
On the site spread remains of cornices and columns from the roman era.
