El-Gulu or as local calls Shah-Gulu is a grand park in south east of Tabriz. There is a big rectangular artificial lake in the middle of the Park with a restaurant. This place used to be a summer palace for the Iranian royal families during the time that Tabriz was the capital of the state and once it was the resident for the crown prince. Nowadays the palace in the middle renovated in the form of a restaurant and a small amusement park is constructed in next to the park. In summer time many residents came to the park and dust hike through the pedestrian pathway around the lake or have their dinner in the Forrest hills next to the lake.
