Ferhat Pasha Mosque (, ), also known as the Ferhadija Mosque, is a mosque in the city of Banja Luka and one of the greatest achievements of Bosnia and Herzegovina's 16th century Ottoman Islamic architecture. The mosque was demolished in 1993 at the order of the authorities of Republika Srpska as a part of ethnic cleansing campaign, and was rebuilt and opened on 7 May 2016. Commissioned by the Bosnian Sanjak-bey Ferhad Pasha Sokolović, the mosque was built in 1579 with money that, as tradition has it, were paid by the Auersperg family for the severed head of the Habsburg general Herbard VIII von Auersperg and the ransom for the general's son after a battle at the Croatian border in 1575, where Ferhad Pasha was triumphant. The mosque with its classical Ottoman architecture was most probably designed by a pupil of Mimar Sinan. There is no written data about the builders who erected the mosque, but from analysing its architecture it appears that the foreman of the works was from Sinan's school since the mosque shows obvious similarities with Sinan's Muradiye Mosque in Manisa, which dates from 1586. Architectural ensemble The ensemble of the Ferhadija mosque consisted of the mosque itself, the courtyard, a graveyard, the fountain, 3 mausoleums ("turbes") and the surrounding wall with the gate. The original canopied wall was pulled down after 1884 and a more massive wall partly of masonry and wrought iron was built with a new gate and a drinking fountain. In the courtyard there was an ablutions fountain ("šadrvan") with a stone basin and twelve pipes. The water for the fountain was brought from a spring that is still known as Šadrvan. Above the stone basin was a decorative wrought iron trellis, and in the 19th century a wooden baldaquin and dome and painted attic in the so-called Turkish baroque style was added which was demolished in 1955. One of three small adjacent mausoleums - Ferhad Pasha Turbe - contained the tombs of Ferhad Pasha Sokolović, the others were for his granddaughter Safi-kaduna, and his ensign. A clock tower ("Sahat kula") was added later. Like most buildings of this type in Bosnia and Herzegovina, the mosque was on a modest scale: wide, long and high at the top of the main dome. The minaret was high. According to legend, when the mosque was completed in 1579, Ferhad Pasha had the masons locked inside
