Persepolis
Darius I built the greatest palace at Persepolis on the western side of platform. This palace was called the "Apadana". The King of Kings used it for official audiences. The work began in 518 BC, and his son, Xerxes I, completed it 30 years later. The palace had a grand hall in the shape of a square, each side long with seventy-two columns, thirteen of which still stand on the enormous platform. Each column is high with a square Taurus (bull) and plinth. The columns carried the weight of the vast and heavy ceiling. The tops of the columns were made from animal sculptures such as two-headed lions, eagles, human beings and cows (cows were symbols of fertility and abundance in ancient Iran). The columns were joined to each other with the help of oak and cedar beams, which were brought from Lebanon. The walls were covered with a layer of mud and stucco to a depth of 5 cm, which was used for bonding, and then covered with the greenish stucco which is found throughout the palaces.
Berenice, Cyrenaica
Founded as a Greek Colony, the city became Roman when Cyrenaica became a Roman province by being bequeathed to Rome by Ptolemy Apion on his death in 96 BC. At first, the Romans gave Berenice and the other cities of the Pentapolis their freedom. By 78 BC however, Cyrenaica was formally organised as one administrative province together with Crete. It became a senatorial province in 20 BC, like its far more prominent western neighbour Africa proconsularis. Diocletian in 296, made Cyrenaica into two provinces: Libya Inferior and Libya Superior (which comprised Berenice and the other cities of the Pentapolis, with Cyrene as capital). Berenice prospered for most of its 600 years as a Roman city
