The octagonal building was the place in which royal guests were hosted during the Zand Dynasty of Iran. It was also used for holding official ceremonies.

It is the burial place of Karim Khan Zand.

In 1936 the pavilion became a museum. It was the first museum which was located outside the capital city of Tehran.  The brick designs, tiling, pictures and big stone dadoes are among the architectural features of the building.

Pars museum is a display of almost thirty handwritten Qurans and a number of magnificent paintings of famous Persian artists. Among the paintings is the well-known Karim Khan’s Smoking Shisha created by Jafar Naqash.

The Nasir al-Mulk Mosque also known as the Pink Mosque is a traditional mosque. It was built during Qajar Dynasty rule of Iran.

The mosque includes extensive colored glass in its facade, and displays other traditional elements such as the Panj Kāse ("five concaved") design.

Although stained glass is now mostly popular in churches, the earliest discovered was in Syria from the 7th century.

We do have evidence of techniques and recipes for obtaining stained glass by the Persian chemist Jabir ibn Hayyan in his book Kitab al-Durra al-maknuna (The Book of the Hidden Pearl) published in the eighth century CE.

Orsi: Persian Stained Glass.  Orsi windows are windows made of a mixture of wood and colorful glass in the Safavid and the Qajar dynasties. Orsi differs from stained glass used in many churches and Ottoman mosques which serve as illuminated images rather than a source of light.

Light is a major feature in many mosques considering it being a major symbol of G-d in Islam.

″Allah is the light of the heavens and the earth″ is mentioned in a chapter in Quran.
