Tehran, June 29 : Archeologists have unearthed an ancient royal structure in the city of Natel located in the northern Mazandaran Province of Iran.
According to a report in Press TV, the quadrangular structure has a number of rooms, surrounded with porticos and a trench, which was filled with water and used to protect the building from attacks.
The monument was constructed with high quality materials and fortified with mortar and three-coat plastering.
Findings show that the building previously had beautiful architectural decorations and was ruined during battles.
The first phase of Natel archeological excavations also yielded a six-meter deep trench, built with large stones, mud, lime and plaster, which surrounds the entire city.
The city of Natel, located at the heart of Iran's northern forests and west of Mazanadran Province, was destroyed during the Safavid era.
