The Revan Pavilion was built in 1635 under Sultan Murat IV (1623-1640) to the memory of the conquest of Yerevan (Revan), on a piece of land gained by reducing the size of the pond that existed on the Sofa-i Hümâyûn since the time of Sultan Mehmet the Conqueror (1451-1481). The pavilion believed to have been conceived by the Head Architect of the period, Koca Kasım Ağa, with an octagonal floor plan has three iwans. The ceiling of the gazebo situated between the two iwans on the east flank overlooking the Tulip Garden is inscribed with some of the verses of the Kaside-i Bürde (a sacred poem).
In 1733, during the reign of Sultan Mahmut I (1730-1754) a foundation library consisting of extremely valuable books, mainly of history, destined to the use of the Imperial Pages (Has Odalılar), was established in the wood cabinets of the pavilion. The library which was further developed by Sultan Osman III (1754-57) and Sultan Mustafa III (1757-1774), has been included in the collection of the Palace Museum Library when the palace was converted into a museum.
The Revan Pavilion is also called sarık odası (turban room) by some sources with reference to the fact that the sacred relics were kept there during the Chamber of the Holy Mantle’s traditional cleaning ceremony attended by the sultans.
