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.
Horreum (Epirus)
“Ancient Orraon is an impressive ancient Molossian acropolis and archeological site where there is much historical value. Where much has been uncovered, such as various houses, a reservoir, cemetery, and roads". Orraon was founded in the 4th century B.C. while Alcetas I was king. This was the period of the Classical period and Hellenistic period. In 167 BC the Romans destroyed Orraon, but was rebuilt shortly afterwards. The city of Orraon lasted for a short period of time. In 37 BC the town had one hundred houses, twelve streets, and a grave yard. Orraon was abandoned by its people. Its inhabitants were forced to settle in Nicopolis which is located in the south western part of Greece. The city of Nicopolis was founded by Augustus after his victory in the Battle of Actium. Horreum was mentioned by the historian Livy.
