Chehel Sotun Palace, whose name poetically translates from Persian as "Forty Columns," is an outstanding architectural monument of the Safavid era. Located in the heart of the ancient city of Qazvin, this elegant pavilion serves as a living reminder of the times when Iran was the center of a powerful empire.

The core of the structure is an elegant square mansion surrounded by an open gallery. The palace earned its unusual name thanks to an optical effect: its 20 tall wooden columns, carved from solid plane tree trunks, are reflected in the clear water of the pool, creating the illusion of forty supports. The building harmoniously combines Islamic and Persian architectural traditions, situated in the middle of what was once an extensive shady garden with fountains.
Today, the palace functions as a museum where visitors can touch history. Inside the pavilion, unique decorative elements, mirror mosaics, and valuable frescoes have been preserved, making Chehel Sotun one of the most significant and recognizable landmarks in the region.
