El Goli Historical Park is one of the most visited sites in Tabriz. It includes a small palace in the middle of a lake. The mansion, which was used as a royal summer resort during Qajar dynasty, presents traditional Iranian architectural style practiced in Azerbaijan. Shah Goli has been translated as “king’s pool”. The construction of this structure was attributed to Aq Qoyunlu dynasty and its development dates back to Safavid era. El-Goli Park was the largest water reservoir to irrigate gardens of east Tabriz before Safavid Dynasty but during this era a wall made of stone was dragged around interior part of the lake. During the Qajar era, some streets, flowers and walk sides were set up around El-Goli Park to decorate this promenade. Some fundamental renovations were done during Pahlavi era by Sayed Baqer Kazemi, the governor of the East Azerbaijan at that time. In the center of the El-Goli Park, there is an octagonal house, which is now used as a reception hall and is famous for El-Goli Palace. In addition to the coffee shop and restaurant located in El-Goli Park, the area around the lake is also a spectacular and beautiful place to walk and relax; there is also a possibility for the visitors to sail inside the lake.
