A team of archaeologists and experts have launched geophysical studies in a historical site near Persepolis to explore residential areas.

Parse is a complex of structures built on the order of Darius I 518 BC and includes palaces, embankments, service sector and drinking water system.

The head of Persepolis historical monument Farhad Kazemi said that a team comprising of archaeologists and geo-physicians have embarked on exploration of residential structures in the southern part of the sprawling complex.

"We uses electronic devices and sensors to determine whether there are residential structures underground. Modern technology helps archaeologists determine the existence of underground structures without undertaking digging operations," he said.

He said the work in southern part of Persepolis is of great importance since excavations carried out between1961-1968, residential quarters were unearthed, making the experts optimistic about the existence of residential areas in other sections of monument.

"The current geophysical study aims to find an answer to the assumption that architectural structures may be discovered in the context of the residential area."
