There are many public buildings of interest, including the whole Kasbah quarter, Martyrs Square (''Sahat ech-Chouhada'' ساحة الشهداء), the government offices (formerly the British consulate), the "Grand", "New", and Ketchaoua Mosques, the Roman Catholic cathedral of Notre Dame d'Afrique, the Bardo Museum, the old ''Bibliothèque Nationale d'Alger''—a Turkish palace built in 1799–1800—and the new National Library, built in a style reminiscent of the British Library.
