# ARHIS > ARHIS is an architectural atlas of Sarajevo and Bosnia and Herzegovina: a map of 146 buildings, five historical periods, and the styles and architects attached to them. The interface is Bosnian by default, with an English toggle. The public site is one map application, not a set of article pages. Permalinks still resolve, and each one opens the same map with that record selected. - An object page is `https://arhis.ba/objekat/{slug}` (example: `https://arhis.ba/objekat/vijecnica`). - A period page is `https://arhis.ba/period/{slug}`. - A style page is `https://arhis.ba/stil/{slug}`. - Names, English names, architects, addresses, and years are searchable from the map. - Core records come from the 2010–2012 arhis.ba archive. Photographs are from Wikimedia Commons, with author and licence cited on the object. Some buildings include a Sketchfab model. ## Periods - [Ottoman period, 1463–1878](https://arhis.ba/period/osmanski): 31 buildings. Styles include early and classical Ottoman, urban and commercial fabric, the Bosnian variant, and bridges. - [Austro-Hungarian period, 1878–1918](https://arhis.ba/period/austrougarski): 38 buildings. Styles include Neo-Renaissance, Neo-Romanesque and Neo-Gothic, Pseudo-Moorish, Romanticism, and Secession. - [Interwar period, 1918–1945](https://arhis.ba/period/izmedju-dva-rata): 5 buildings. - [Socialist period, 1945–1990](https://arhis.ba/period/socijalizam): 36 buildings, mostly Modernism, with some Postmodernism. - [Contemporary period, 1992–present](https://arhis.ba/period/savremeni): 36 buildings, including contemporary architecture, contemporary Islamic architecture, and memorials and museums. ## Optional - [Atlas](https://arhis.ba/): the map itself. - [Archived source portal](https://web.archive.org/web/20120228054825/http://www.arhis.ba/): the 2012 snapshot the core records were taken from.
