This building, which in colloquial language is called Narenj Castle, is one of the most important relics of the province dating back to the period before the advent of Islam to Iran, and has been recorded as one of the national buildings. This ancient castle has been constructed on the top of Galeen hill and overlooks the city.

The historical Khorheh Village is located to the west of main road running between Tehran and Esfahan. To the west of which is an archaeological relic related to the Seleucidian era.

This cave is located in the heights facing the Haj Arah village of Zanjan. At present no road way facilities are provided and the only way to get there is to trek. This large cave has come about from limestone deposits. Remnants in these caves date back thousands of years at least 16-30000 years BC.

This is one of the ancient citadels of this township. But unfortunately it is nearly depleted. This structure most probably belongs to pre-Islamic period, and was used during the same era.

The said cave is located in the heights of the Kharmanehsar Mountains in the village of Shah Neshan. A type of granite and white limestone have formed columns and hangings (Stalagtites and Stalagmites) very similar to those of a chandelier, suspended from the roof of the cave. Needless to say this natural feature has added to its beauty.
