Home›Government and Civic Buildings›Completed Year›By Century›20th centuryBrowse By20th centuryCompleted year orders buildings by the year construction actually finished, which can be long after work began. The Sagrada Familia's central tower, Wikipedia notes, "reached structural completion on 20 February 2026," well over a century after ground was first broken in 1882. Browsing by completed year separates a building's finish date from its start date.Facts20th centurySourcesComments (0)Reader Challenges (0)FactsComparisonEra of EmergenceWell-attested1144 CE 1Origin RegionWell-attestedItaly (Rome) 120th centuryFilter Results56 entriesArchitectAllKenzo Tange (1)Le Corbusier (1)Oscar Niemeyer (2)Building FamilyAllCity and Town Halls (9)Courts and Judicial Buildings (4)Executive, Head-of-State and Diplomatic Buildings (7)Government Building Types and Terms (Other) (1)Legislative, Parliament and International Body Buildings (25)Prisons and Detention Facilities (1)Public Utility and Civic Service Buildings (9)StyleAllArchitectural Eclecticism (1)Art Deco (3)Art Nouveau (1)Baroque Architecture (1)Baroque Revival Architecture (1)Beaux-Arts Architecture (2)Brutalism (2)Cape Dutch Architecture (1)Edwardian architecture (2)Gothic Revival (3)Greek Revival Architecture (1)Indo-Saracenic Architecture (1)Modernist Architecture (8)National Romantic Style (2)Neoclassical Architecture (9)Nordic Classicism (1)Postmodern Architecture (4)Renaissance Architecture (1)Romanesque Revival Architecture (1)Rustic Architecture (6)Second Empire Architecture (1)Stalinist Architecture (1)Stripped Classicism (4)Swiss chalet style (1)Venetian Gothic Architecture (1)Vietnamese Architecture (1)MaterialAllBrick (5)Concrete (1)Granite (4)Limestone (2)Marble (5)Masonry (4)Reinforced Concrete (1)Sandstone (4)Steel (4)Stone (8)Stucco (1)Timber (4)Building TypeAllBuilding of public administration (1)Capitol building (4)City Hall (7)City hall (former post office) (1)city hall, government offices (1)Comfort station (7)Courthouse (1)Former school building (1)Fort (1)Government building (2)Government Complex (1)Government offices (1)House (1)Information kiosk (1)Legislative Building (2)Legislative building, seat of parliament (1)Museum (1)neo-Gothic parliament building (1)Office Building (1)Palace (2)Parliament Building (10)Parliament complex (1)Parliament house, now a museum (1)Presidential office building (1)Presidential Residence (1)Seat of government and presidential offices (1)Seat of the United Nations Office at Geneva (1)Town Hall (1)Villa (1)Standing StatusAllStanding (56)GroupAllCity and Town Halls (9)Courts and Judicial Buildings (4)Executive, Head-of-State and Diplomatic Buildings (7)Government Building Types and Terms (Other) (1)Legislative, Parliament and International Body Buildings (25)Prisons and Detention Facilities (1)Public Utility and Civic Service Buildings (9)PlaceAllAustralia (1)Australia (2)Bangladesh (2)Brazil (3)Canada (3)China (1)Cuba (1)Czechia (1)Denmark (1)Dominican Republic (1)Finland (2)Germany (1)Hungary (1)India (2)Japan (2)Lithuania (1)Mexico (1)Poland (1)Portugal (1)Romania (1)South Africa (2)Spain (1)Sweden (3)Switzerland (2)Thailand (1)Turkey (1)Ukraine (1)United Kingdom (1)United States (15)Vietnam (1)BrowseCompareSelect all 56Australian Parliament House20th centuryBear Lake Comfort Station20th centuryCape Town City Hall20th centuryCapitolio Nacional20th centuryCentre Block20th centuryChandigarh Capitol Complex20th centuryChicago City Hall20th centuryComfort Station (Milton, Massachusetts)20th centuryComfort Station No. 6820th centuryComfort Station No. 7220th centuryCopenhagen City Hall20th centuryFederal Palace of Switzerland20th centuryFinland Parliament House20th centuryGovernment House, Bangkok20th centuryGrand National Assembly Building20th centuryGreat Hall of the People20th centuryHungarian Parliament Building20th centuryIndependence Palace20th centuryJatiya Sangsad Bhaban20th centuryKramar's Villa20th centuryLos Angeles City Hall20th centuryMarin County Civic Center20th centuryNational Assembly Building, Dhaka20th centuryNational Congress of Brazil20th centuryNational Congress Palace20th centuryNational Diet Building20th centuryNew Town Hall, Munich20th centuryOld Parliament House, Canberra20th centuryPalace of Nations20th centuryPalace of the Parliament20th centuryPalacio de Cibeles20th centuryPalacio do Planalto20th centuryPalacio Nacional20th centuryParliament Buildings, Stormont20th centuryParliament House, Canberra20th centuryParliament House, Stockholm20th centuryPhiladelphia City Hall20th centuryRainbow Point Comfort Station and Overlook Shelter20th centuryRashtrapati Bhavan20th centuryRiksdag Building20th centurySan Francisco City Hall20th centurySao Bento Palace20th centurySeimas Palace20th centurySejm and Senate Complex20th centurySpring Valley School District 120 Building20th centuryStockholm City Hall20th centuryString Lake Comfort Station20th centurySunrise Comfort Station20th centuryTamminiemi20th centuryThunder Bay Tourist Pagoda20th centuryTokyo Metropolitan Government Building20th centuryToronto City Hall20th centuryUnion Buildings20th centuryUnited States Bullion Depository20th centuryUnited States Supreme Court Building20th centuryVerkhovna Rada Building20th centurySources1.
