Madrasah of Bishapur

 Within the area of the royal citadel, there is a building constructed in the style of Islamic madrasahs. Most probably it is of a Sassanian origin but has changed its function during the Islamic era under the Buyid dynasty who ruled Iran in the 4^th century AH. From an architectural point of view, the madrasah had been built in a cruciform but apparently after an earthquake it has undergone repairs which have changed its shape. The unearthed pedestals of the madrasah are adorned with floral motifs and Koranic verses. Seemingly building materials belonging to royal Sassanian structures have been used in the construction of the school similar to the mosque especially in thresholds or doorways.
