The arch marked the border between Tripolitania and Cyrenaica, and was located on the Via Balbia (actual Libyan Coastal Highway) near Ra's Lanuf.
[1] The landmark was named after the legendary Philaeni brothers of Carthage, who chose to be buried alive on that spot in order to gain this border for their home town.
It bore two giant bronze statues of the brothers, represented as buried alive, surmounted by a stylised altar, mocking one of the disappeared Arae.
Revolutionary leader Muammar Gaddafi, who considered the landmark as a sign of the Italian domination of Libya, demolished the arch using dynamite in 1973.
The two bronze statues of the Philaeni brothers and parts of the marble reliefs are now located in a small museum in Medinat Sultan, around 50 kilometres (31 mi) from Sirte.
