Founded by the Sassanid king Shapur I in the 3rd century AD, Qazvin prospered under the Seljuk rulers, who erected many fine buildings. It had a second, much later burst of prominence when the second Safavid king, Tahmasb I (r 1524–76), transferred the Persian capital here from Tabriz. A great patron of the arts, his ambitious architectural plan for Qazvin proved to be only a dress rehearsal for Esfahan, where his successor, Abbas I, set up court in 1598.
Qazvin is famed for carpets and seedless grapes. The city was once capital of all Iran and has a considerable sprinkling of minor sights, but for most Western travellers its foremost role is as a launch point for excursions to the famous Castles of the Assassins in the marvellous Alamut Valley.
This pavilion is located in the old Qazvin city.when Shah Tahmasb,the Safavid king changed and transferred the capital from Tabriz to Qazvin due to the treat of Ottoman Turks ,He ordered to construct a square shaped garden and a mansion and a hall in the middle of it according to the design of a Turkish architect with a very small checkered style indicating very beautiful and attractive wooden windows.
This octagonal building was renovated later by the governor of Qazvin called Mohammad Baqer Sa’ad-o Saltaneh and was named as Chehel Sotoun.

the mausoleum of one of the numerous sons of the eighth Shiite imam is a very stunning building in Qazvin.
The shrine received its first architectural prominence in 1220s.During the reign of Safavid kings it received some additional spaces and became a magnificent architectural complex and was reconstructed later in 1840s.
A vast courtyard, flanked by the northern and southern gates, provides enough space to gaze at the edifice.Of all the entrances, the northern one is an imposing piece of work. Geometrical patterns, decorative tile-works, tall gates, and 6 mini-minarets have bestowed the northern entrance a unique style dating back to the Qajar dynasty.
Alamut historical fort is located in the northeast of Gazarkhan village in Qazvin province on 2163 meters above sea level and with about 400 stone steps, this fort has only one entrance from its northeast corner. There is a ditch on the southern slope of the mountain that blocks any way of penetration. The length of the fort is about 120 meters and its width is between 10 and 35 meters. When we stand at the top of the fort, we can see a distance of about 10 km. All around this fort, there is a precipice, in fact, the choice of geography and architecture of the castle is invincible. This fortress is the residence of Hassan Sabah, the leader of the Ismaili sect, known as Hassan Sabah Fortress. He was born in Qom to a Shiite family and spent some time in Neishabour. He went to Egypt and studied for 3 years, after which he returned to Iran and went to Alamut, where he settled. He died of an illness after living in Alamut Castle with his family for 35 years. Years later, the Mongols set fire to his tomb
