Taghbestan is one of the most prominent historical sites in the west of Iran. This historical site with several lithographic works from different historical periods shows the symbol and guidance of the past culture and customs of Iranians from the third century AD onwards. The most significant works in this place are two arches with different dimensions next to each other. The big arch belongs to the reign of Khosrow Parviz and the small arch belongs to Shahpour II and Shahpour III are other commanders in the history of ancient Iran. In the margins of these two arches, the winged angels of horses, elephants and boats can be seen, which according to archaeologists are symbols of celebration in the culture of that time. Apart from these works, the presence of another large lithograph taken a few meters to the left of the small arch shows a victory of Ardashir II over his enemy and standing on its coffin, which archaeologists consider the king of Rome, taking a veiled ring from Ahura is a Mazda. At the top of this lithograph, there are several other works, including a 78-step staircase, as well as a newly discovered lithograph in the form of a man praying, all of which are among the attractions of this historical area. This place is located in the northwest of Kermanshah and at the end of Bostan Arch Boulevard, which is another beautiful place in this ancient city. Other beautiful landscapes of this historical site and the existence of a mirage of the same name, namely Taq-e Bostan, can be mentioned, which borrows its abundance of water from the soaring mountains of Kermanshah, which is miles away, ie the Peru mountain range.
Unfortunately, today, Bostan Arch is not as beautiful as it used to be due to the manipulations that were done to register it in the World Heritage Organization. The views are limited and the restaurants outside the grounds are completely cluttered and uneven, drawing visitors into a tortuous place with ugly closets, while in the not-so-distant past the grounds were very wide and the lake had fences. It was beautiful that the eastern part was connected to the west by a street full of towering trees, but today, due to these manipulations, even the number of visitors to Kermanshah has been very limited.
