Archaeologists have discovered the foundations of the Roman triumphal arch in ancient Trimontium (the present city of Plovdiv in Bulgaria).
The remains date back to the 1st century CE. The base of the arch (3.6 meters wide) is located on both sides of a well-preserved ancient street. The facility is made of sandstone blocks weighing 3-4 tons each. The street was about 7 meters wide. Interestingly, scientists found evidence that the road was widened.
Trimontium was the main Roman city in Thrace. Numerous public utility structures were built in the city, incl. theaters, thermal baths or stadiums. Earlier, before the Roman rule, the city was called Philipopolis after Philip II of Macedon conquered it.
