The end of Ali Pasha, who dared to defy the sultan, is also the ending for the Serai. The shining palace becomes the Ottoman Headquarters. When it was destroyed by fire in 1870, the Military Hospital was built in its place, but it was also demolished and the Royal Pavilion was erected in 1958. Here, on the ground floor, frescoes, icons and relics of Byzantine and Post-Byzantine times, dated from the 4th to the 19th century, are hosted today.
