Chehel Sotun, Qazvin

Chehel Sotun, originally named Kolah Farangi Mansion is a Safavid era royal pavilion located in Qazvin, Iran.

Its construction is attributed to Tahmasp I, who transferred the capital of Iran from Tabriz to Qazvin in 1548, and was repaired and remodeled during Qajar era.

Today, it is one of the two remaining Safavid royal structures remaining in the city, the other one being the Ali Qapu gate, and is used as a museum of calligraphy.
