The Arc de Triomphe of Marcus Aurelius is located in Libya, in the city of Tripoli, at the northeast entrance to the Old City. The arch, named after the Roman emperor Marcus Aurelius, was actually installed to commemorate the victories of his brother and co-ruler Lucius Vera in the Roman-Parthian war of 161-166. In 164, the Roman capital led by Lucius Vera took the capital of the Parthian kingdom - the city of Ctesiphon, and in honor of this event in 165 in the city of Ea (present Tripoli) a triumphal arch was erected. The arch is made of marble, its facades are oriented to the northwest, northeast, southeast and southwest, and statues of Lucius Vera and Marcus Aurelius were installed in four niches (some of them were discovered during excavations in the 19th century). The arch was crowned by a gilded sculpture depicting two emperors in a chariot. The facades were decorated with bas-reliefs depicting griffins, sphinxes and the goddess Roma, personifying the eternal city of Rome. On one of the facades there is an inscription stating that the arch was erected on the initiative of the local magistrate (official in Ancient Rome) Guy Calpurnia Celsius. The arch of Marcus Aurelius was restored in 1914-1918 by the Italian colonial authorities, in the 30s of the XX century the area around the monument was landscaped by the Italian architect Florestano Di Fausto.
