visible. An official term for the rationale is spolia. The mosque was called the djami of Pasha Gazi Kassim, and djami means mosque in Arabic. After Turks and Muslims were expelled and massacred from Budapest, the site was reoccupied by Christians and reformed into a church, the Inner City Parish Church (Budapest). The minaret and Turkish entranceway were removed. The shape of the architecture is its only hint of exotic past—"two surviving prayer niches facing Mecca and an ecumenical symbol atop its cupola: a cross rising above the Turkish crescent moon". After 1686, the Baroque architecture designated the dominant style of art in catholic countries from the 17th century to the 18th century. There are many Baroque-style buildings in Budapest and one of the finest examples of preserved Baroque-style architecture is the Church of St. Anna in Batthyhány square. An interesting part of Budapest is the less touristy Óbuda, the main square of which also has some beautiful preserved historic buildings with Baroque façades. The Castle District is another place to visit where the best-known landmark Buda Royal Palace and many other buildings were built in the Baroque style. The Classical architecture and Neoclassical architecture are the next in the timeline. Budapest had not one but two architects that were masters of the Classicist style. Mihály Pollack (1773–1855) and József Hild (1789–1867), built many beautiful Classicist-style buildings in the city. Some of the best examples are the Hungarian National Museum, the Lutheran Church of Budavár (both designed by Pollack) and the seat of the Hungarian president, the Sándor Palace. The most iconic and widely known Classicist-style attraction in Budapest is the Széchenyi Chain Bridge. Budapest's two most beautiful Romantic architecture buildings are the Great Synagogue in Dohány Street and the Vigadó Concert Hall on the Danube Promenade, both designed by architect Frigyes Feszl (1821–1884). Another noteworthy structure is the Budapest Western Railway Station, which was designed by August de Serres and built by the Eiffel Company of Paris in 1877. Art Nouveau came into fashion in Budapest by the exhibitions which were held in and around 1896 and organised in connection with the Hungarian Millennium celebrations. Art Nouveau in Hungary (Szecesszió in Hungarian) is a blend of several architectural styles, with a focus on Hungary's specialities. One of the leading Art Nouveau architects, Ödön Lechner (1845–1914), was inspired by Indian and Syrian architecture as well as traditional Hungarian decorative designs.
