How three structural innovations allowed medieval builders to reach for heaven
Pointed arch: directs weight downward more efficiently than round arch → can be taller. Ribbed vault: concentrates weight on specific points (ribs) → walls between ribs can be thinner. Flying buttress: external arch carries lateral thrust away from wall → wall can have windows. Result: enormous stained glass windows, unprecedented height. Chartres Cathedral (1194–1220): flying buttresses, north and south rose windows, three portal sculptures. Notre-Dame de Paris (1163–1345): classic Gothic. Sainte-Chapelle (1248): walls almost entirely glass. Gothic revival: 19th century (Pugin, Viollet-le-Duc, Westminster Palace).
The rebirth of classical architecture — and the engineering genius that launched it
Filippo Brunelleschi: Florence Cathedral dome (1420–1436) — largest brick dome ever (42 m), no centering (scaffold), herringbone brickwork, double shell. Studied Pantheon. Invented linear perspective (~1415). Also: Ospedale degli Innocenti (Florence) — first Renaissance building, rational arcade. Leon Battista Alberti: De Re Aedificatoria — codified Renaissance architecture theory. Palazzo Rucellai (Florence): classical pilasters applied to palace facade. Palladio (16th c.): Villa Rotonda — perfect symmetry, porticoes on all 4 sides. Palladianism influenced English architecture and US (Jefferson's Monticello).
Bauhaus
Bauhaus 1919–1933: form follows function — unified fine art, craft, and industrial design. Gropius founded it.
Bauhaus
The most influential design school in history — still shaping everything from fonts to furniture
Walter Gropius founded Bauhaus (1919, Weimar, Germany). Motto: unified art and craft with industrial production. Masters: Paul Klee, Wassily Kandinsky, László Moholy-Nagy, Marcel Breuer, Mies van der Rohe. Bauhaus building (Dessau, Gropius, 1925–1926): glass curtain wall, flat roofs, steel frame — manifesto in architecture. Typefaces (Bauhaus sans-serif), furniture (Breuer's Wassily Chair), textiles (Anni Albers). Nazis closed it 1933 → masters emigrated to USA → spread influence globally. Harvard, IIT, Black Mountain College. 'Less is more' modernist legacy.
America's most influential architect — buildings that grow from their sites
Prairie Style (early 1900s): low horizontal lines, overhanging eaves, open floor plans, integrated with landscape. Robie House (Chicago, 1910). Fallingwater (Mill Run PA, 1935): cantilevered concrete over waterfall — organic integration. Guggenheim Museum (NYC, 1959): continuous spiral ramp — controversial for displaying art. Johnson Wax Building: mushroom columns. Usonian houses: affordable, single-story, radiant floor heating. Influence: organic architecture, open plan (eliminated separate rooms), integration of interior and exterior. 532 completed buildings. Taliesin (Wisconsin) and Taliesin West (Arizona): home/studio/school.
Art Nouveau
Art Nouveau (~1890–1910): organic flowing forms, natural motifs, total design. Gaudí (Barcelona), Klimt (Vienna), Mucha.
Art Nouveau
The first truly international style — when nature's curves invaded every designed object
Characteristics: sinuous curves, organic plant forms, female figures, integration of ornament and structure, total artwork (Gesamtkunstwerk). Architectural: Antoni Gaudí — Sagrada Família (Barcelona, still unfinished), Casa Batlló, Park Güell (nature-derived forms, Catalan modernisme). Hector Guimard: Paris Métro entrances. Victor Horta: Brussels townhouses (iron exposed decoratively). Graphic design: Alphonse Mucha (Czech, Paris posters). Vienna Secession: Klimt, Olbrich (Secession Building), Wagner. Rejected historical revivalism — created new ornamental vocabulary from nature. Short-lived: WWI and Modernism's functionalism ended it.
Modernist Architecture
Modernism: Le Corbusier (5 points), Mies van der Rohe (less is more), International Style. Glass, steel, flat roofs.
Modernist Architecture
The 20th century's dominant architectural ideology — and why it succeeded and failed
Le Corbusier's Five Points: pilotis (raised on columns), free plan, free facade, horizontal windows, roof garden. Villa Savoye (1929): machine for living. Unité d'Habitation (Marseille): urban megablock. Chandigarh, India: planned capital. Mies van der Rohe: Barcelona Pavilion (1929) — flowing space, travertine/glass/steel. Seagram Building (NYC, 1958). International Style: glass curtain wall, steel frame, minimal ornament, rectilinear. Criticism: inhuman scale, uniform global aesthetic, failed housing projects (Pruitt-Igoe demolished 1972). Postmodern reaction (Robert Venturi, 1966): 'Less is a bore.'
The backlash against modernism's severity — and architecture that smiled again
Robert Venturi: Complexity and Contradiction in Architecture (1966) — 'Less is a bore.' Learning from Las Vegas (1972): decorated shed vs duck. Charles Moore: Piazza d'Italia (New Orleans) — playful classical fragments. Michael Graves: Portland Building (1982) — colored keystones, classical references, color. Philip Johnson: AT&T Building (NYC, 1984) — broken pediment (Chippendale top). James Stirling: Neue Staatsgalerie (Stuttgart). Frank Gehry: deconstructivism — Guggenheim Bilbao (1997, titanium curves), Walt Disney Concert Hall. Zaha Hadid: fluid, parametric. Rem Koolhaas: OMA.
Islamic Architecture
Islamic architecture: arabesque, muqarnas (honeycomb vaulting), geometric tilework, no human images in sacred spaces.
Islamic Architecture
An architectural tradition of extraordinary geometric complexity and spiritual abstraction
Prohibition on figurative art in religious contexts → geometric abstraction, arabesque (infinite interweaving plant motifs), calligraphy. Key elements: muqarnas (stalactite/honeycomb vaulting), iwan (vaulted portal), minaret (tower for call to prayer), dome. Great Mosque of Córdoba (784–987 CE): forest of columns, double arches (red/white voussoirs). Alhambra (Granada, 13th–14th c.): Nasrid palaces — muqarnas, tile dado (zellij), stucco panels, water features. Dome of the Rock (Jerusalem, 691 CE): earliest surviving Islamic monument. Taj Mahal (Agra, 1632–1648): Mughal — white marble, charbagh (fourfold garden), perfect symmetry.
Architecture since the 1990s — computers, sustainability, and the global iconic building
Deconstructivism: Gehry (Bilbao Guggenheim), Hadid (MAXXI Rome, Heydar Aliyev Centre), Daniel Libeskind (Jewish Museum Berlin), Peter Eisenman. Parametric design: computers generate complex curved forms impossible to draw by hand — Hadid's practice. Sustainable: Herzog & de Meuron (Basel), LEED certification, living walls, passive house. Bilbao effect: iconic building revitalizes a city economically. High-tech: Renzo Piano (Centre Pompidou — with Rogers, 1977), Norman Foster (Gherkin London, HSBC Hong Kong), Richard Rogers. Critical regionalism (Frampton): modern methods + local materials/climate. The starchitect phenomenon: global celebrity architects.
Japanese Architecture
Japanese architecture: impermanence, wabi-sabi, modular tatami grid, shoin style, Zen gardens. Katsura Imperial Villa.
Japanese Architecture
A tradition of refined simplicity — when impermanence and emptiness are the highest ideals
Ise Grand Shrine: rebuilt every 20 years (since 4th c. CE) — impermanence as spiritual practice, preserves ancient construction techniques. Modular planning: tatami mat (90×180 cm) determines room dimensions. Shoin-zukuri style: tokonoma (alcove for art), fusuma (sliding screens), engawa (veranda). Katsura Imperial Villa (Kyoto, 17th c.): asymmetrical, flowing movement through space, borrowed scenery (shakkei). Zen gardens: raked gravel, stones — meditation space, reduce to essentials. Influence: Bauhaus, Mies (grid + open plan), minimalist architecture. Kengo Kuma, Tadao Ando (concrete + nature + light).
Romanesque Architecture
Romanesque: thick walls, round arches, barrel vaults, dark interiors — fortresses for God. 1000–1150 CE.
Romanesque Architecture
The heavy, fortress-like Romanesque style — and why it looks that way
Romanesque (c.1000–1150 CE): round arch, thick stone walls, small windows (no flying buttresses → walls carry all load), barrel vault, dark interiors. Pilgrimage churches: Santiago de Compostela, Saint-Sernin (Toulouse) — wide naves for pilgrims. Tympanum sculpture over portals: Last Judgment (Autun, Gislebertus). Cluny III: largest Romanesque church (destroyed French Revolution). Norman Romanesque in England: Durham Cathedral (1093) — early ribbed vault, transitional to Gothic. Regional variety across Europe. Transition: pointed arch appears (Durham, 1093) before Gothic is formally named.
