During the reign of Shah Tahmasp I, the capital of the Safavid dynasty changed from Tabriz to Qazvin. Later on, Qazvin City had major changes and many buildings were constructed there, including this two-story Palace. Paintings on the walls of Chehel Sotoun Palace in Qazvin are among the main decorations of this palace; other decorations include doors with Khatam-Kari decoration (Khātam is an ancient Persian technique of inlaying.
It is a version of marquetry where art forms are made by decorating the surface of wooden articles with delicate pieces of wood, bone, and metal precisely-cut intricate geometric patterns), tiling and gilding. The calligraphy museum is currently held at Chehel Sotoun Palace in Qazvin and exhibits calligraphic works in a variety of styles and from different artists.
