Topkapı Palace
Following the end of the Ottoman Empire in 1923, Topkapı was transformed into a museum by a government decree dated April 3, 1924. The Topkapı Palace Museum is administered by the Ministry of Culture and Tourism. The palace complex has hundreds of rooms and chambers, but only the most important are accessible to the public today, including the Ottoman imperial harem and the treasury, called "hazine" where the Spoonmaker's Diamond and Topkapi Dagger are on display. The museum collection also includes Ottoman clothing, weapons, armor, miniatures, religious relics, and illuminated manuscripts like the Topkapi manuscript. The complex is guarded by officials of the ministry as well as armed guards of the Turkish military. Topkapı Palace is part the Historic Areas of Istanbul, a group of sites in Istanbul that were added to the UNESCO World Heritage Site in 1985.
Ioannina Castle
The main surviving part of Ali's palace is the so-called "Treasury" (Θησαυροφυλάκιο) to the north, a square building of unidentified use. A domed space adjacent to it was later converted into the small church of the Holy Unmercenaries (Άγιοι Ανάργυροι). The Treasury was restored in 1989–90 and houses an exhibition on the history and methods of silversmithing in Ioannina and its wider area, for which the region was famous in Ottoman times. Other surviving or excavated structures are the kitchens, dating to the early 19th century, located in the northwestern part of the citadel, which now serve as a refectory; the gunpowder store to the northeast of the Fethiye Mosque, which today serves as an educational space, with a ruined building of unknown purpose between it and the kitchens, as well as the ruined base of another large Byzantine-era circular tower; a large two-storey building northeast of the Treasury, possibly a barracks or an unidentified part of the palace, which survives only in half its original length, and now serves as a cultural and exhibition space; and a small bath complex to the north.
