In 1850 the architects Fossati built a new maqsura or caliphal loge in Neo-Byzantine columns and an Ottoman–Rococo style marble grille, connecting to the royal pavilion behind the mosque.[1] The new maqsura was built at the extreme east end of the northern aisle, next to the north-eastern pier. The existing maqsura in the apse, near the mihrab, was demolished.[101] A new entrance was constructed for the sultan: the Hünkar Mahfili.[101] The Fossati brothers also renovated the minbar and mihrab.
