Mostar has architecturally noteworthy buildings in a wide range of styles. Historicist architectural styles reflected cosmopolitan interest and exposure to foreign aesthetic trends and were artfully merged with indigenous styles. Examples include the Italianate Franciscan church, the Ottoman Muslibegovića house, the Dalmatian Corovic House and an Orthodox church which was built as gift from the Sultan.
The Ottomans used monumental architecture to affirm, extend and consolidate their colonial holdings. Administrators and bureaucrats – many of them indigenous people who converted from Christianity to Islam – founded mosque complexes that generally included Koranic schools, soup kitchens or markets.
Out of the thirteen original mosques dating from the 16th and 17th centuries, seven have been lost during the 20th century for ideological reasons or by bombardment. One of the two 19th-century Orthodox churches has also disappeared, while the early 20th-century synagogue, after suffering severe damage in the World War II, has been converted into a theatre. Several Ottoman inns also survived, along with other buildings from this period of Mostar's history, such as fountains and schools.
The majority of administrative buildings are from the Austro-Hungarian period and have neoclassical and Secessionist characteristics. A number of surviving late Ottoman houses demonstrate the component features of this form of domestic architecture - upper storey for residential use, hall, paved courtyard, and verandah on one or two storeys. The later 19th-century residential houses are predominantly in neoclassical style.
A number of early trading and craft buildings still exist, notably some low shops in wood or stone, stone storehouses, and a group of former tanneries round an open courtyard. Once again, the 19th-century commercial buildings are predominantly neoclassical. A number of elements of the early fortifications are visible. Namely the Hercegusa
