Do not miss El Goli Park in Tabriz (former Shah Goli) as it's the grand "People's Lake" and a pleasant hillside garden and park around a 5 Ha water body.
El Goli is only 4 km downstream of Tabriz to the south, so it's a popular weekend destination for locals to relax for breakfast or afternoon activities. Especially popular is the hill on the eastern side of the park with some steps leading down to a pool and a fountain flowing from the hilltop. The square lake is said to be 12m deep surounding a grand hexagonal palace building.
Early history is not clear however it's most widely beleived the original purpose of Shah-Goli Lake was a water resource for agricultural purposes. The pool itself is said to have been built during the reign of Aq Qoyunlu kings. However it was extended by the Safavids, before being used as a summer palace during the Qajar dynasty when the prince of Iran officially resided in Tabriz. Afterwards the lake was reconstructed during the reign of Mohammad Reza Pahlavi (Last Shah). Though after the Iranian Revolution of 1979, removing the Shah's name from all urban planning became a sort of norm. So the name of Shah-Goli was changed to El-Goli Park in Tabriz in official documents, yet remains commonly called Shah-Goli by locals.
