buildings. All moveable historical objects discovered by the Polish expedition were transferred to Warsaw upon the consent of the Soviet archaeological office. Tell Atrib Professor Michałowski wanted to continue the works in Egypt after World War II. He was able to resume the exploration of Edfu but the French were banned from excavating in Egypt. Professor Michałowski decided that since the French archaeologists had not returned to Edfu without their Polish colleagues during World War II, he would also not go back there without them. Tell Atrib – Athribis, a capital city of the 10th nome of the Lower Egypt, today known as Benha – became a new excavation site. The works were performed from 1957 to 1969. The remains of an ancient water supply system of the Roman city were discovered, as well as remains of sacred buildings of the Late Period, foundations of Ahmose temple, a deposit, furnaces for limestone and Roman baths. Palmyra On 4 May 1959 a group of Polish archaeologists headed by Professor Michałowski started excavation works in Palmyra. The works of Polish archaeologists focused on two sections. The first one was the so-called camp of Diocletian in the western part of the city, where the exploration covered the area between the Praetorian Gate and the Tetrapylon, on the square in front of the so-called Temple of the Standards and inside the temple itself. The city walls were also investigated and a fragment of the Praetorian Road was excavated. On the second section, in the so-called Valley of Tombs, i.e. Palmyrene necropolis, tombs of Zabda, Alaine and Julius Aurelius Hermes were discovered. The excavations enabled determination of the urban development of the city as well as the dating of the revealed buildings based on the epigraphic material they contained. A discovery of a treasure consisting of jewelry and 27 golden solidus coins dating back to the times of Phocas, Heraclius and Constans was a sensational success. So great was the value and significance of the discovered material that since 1966 an annual paper titled "Studia Palmyreńskie" has been published in Warsaw and is still published today. Polish archaeologists became experts in the exploration of ancient Palmyra. Alexandria Excavations on Kom el-Dikka in Alexandria began in 1960. Polish archaeologists comprised the first foreign mission which managed to obtain a permit for exploration of Alexandria. Groups of Italian, English and German scientists worked for the Greek-Roman Museum
