Spot an Architectural Style: 8 Looks Decoded
Three cues and you have it
Most people can name a building beautiful or ugly without knowing why. This reference gives you the vocabulary to go further. Each of the eight styles below has a precise historical window, a single iconic landmark to picture, and three visual cues sharp enough to identify it from across the street. The styles are ordered by era, from the mid-nineteenth century to the mid-twentieth, covering the buildings most likely to appear in any city built between 1840 and 1970.
How to use this page
Start with the roofline: steep gables point to Gothic or Victorian; flat lines point to Modernism. Then look at the surface: ornament signals the classical traditions; bare concrete or glass signals the twentieth century. Then look at columns: Greek-style columns narrow the field to Neoclassical or Beaux-Arts. Once you have those three observations, the table below closes in on the answer in seconds.
Gothic Revival
1840 to 1875. Pointed arches on every window and door; steeply pitched roof; stone tracery framing t
Neoclassical
1750 to 1850. Columns in rows (Doric, Ionic, or Corinthian); triangular pediment over the main entra
Beaux-Arts
1880 to 1920. Grand symmetrical facade with paired columns; carved sculptural figures above windows;
Art Nouveau
1890 to 1910. Flowing curved lines on balconies and ironwork; nature motifs (vines, flowers, insects
Art Deco
1925 to 1940. Stepped or ziggurat roofline; chevron and sunburst patterns in stone or metalwork; str

Mid-Century Modern
1945 to 1969. Low flat or butterfly roof with wide overhanging eaves; floor-to-ceiling glass; honest
Gothic Revival: the pointed arch as moral argument
The pointed arch had been dormant since the medieval cathedrals. A.W.N. Pugin and John Ruskin revived it in the 1840s, arguing that Gothic honesty of construction was morally superior to the cold geometry of Neoclassicism. The result appeared across churches, universities, and public buildings. The Houses of Parliament in London, begun in 1840 after a fire destroyed the original, became the definitive statement. Look for steeply pitched roofs, towers with battlements, lancet windows (a tall narrow arch with a pointed top), and stone tracery (the carved web filling the upper part of a window).
Neoclassical: columns for the age of reason
Neoclassicism arrived in the eighteenth century as a deliberate riposte to the excess of the Baroque period. Its models were the temples of ancient Greece and Rome, championed by Thomas Jefferson and French Enlightenment architects as the natural language of democratic institutions. The style reached its peak in public buildings: courthouses, banks, and capitals. Three cues identify it: a portico with a row of classical columns, a triangular pediment sitting above them, and a near-total absence of carved decoration on the wall surface. The Brandenburg Gate in Berlin (1791) and the Pantheon in Paris (1790) are the cleanest examples.
Beaux-Arts: the grammar of civic grandeur
The Ecole des Beaux-Arts in Paris trained a generation of American architects from the 1880s onwards, and they brought the style back to Washington DC and New York. Beaux-Arts takes Neoclassicism and compounds it: more columns, grander staircases, allegorical sculpture filling every surface above the column line. Grand Central Terminal (1913) and the New York Public Library (1911) are the two most-visited examples. The giveaway is the combination of monumental scale, strict symmetry, and ornament that reads as almost excessive even by classical standards.
Art Nouveau: the building as living organism
Art Nouveau lasted barely twenty years but left some of the most recognisable buildings in Europe. It rejected historical revival entirely and turned instead to nature, translating the curves of plant stems and insect wings into stone, iron, and ceramic tile. Antoni Gaudi's Casa Batllo in Barcelona (1906) and Victor Horta's buildings in Brussels are the canonical examples. The cues are all about the line: no straight edge where a curve can replace it, ironwork balconies that look cast rather than hammered, and facade decoration drawn from botany rather than classical mythology. The style died as quickly as it arrived, killed by the First World War's austerity.
Art Deco: modernity dressed for the occasion
Art Deco kept the ornamentation that Modernism was about to abolish, but replaced classical motifs with geometry borrowed from Aztec temples, Egyptian tombs, and the age of the machine. The Chrysler Building (1930) remains the peak example: its crown of seven radiating arched windows, each clad in stainless steel Nirosta, makes it identifiable from across Manhattan. The three cues are the stepped roofline (each setback creating a smaller floor above), the chevron or sunburst pattern applied to any flat surface available, and the vertical emphasis that makes even a low building seem to aspire upward. Miami Beach has the highest concentration of Art Deco buildings in the world.
International Style: glass and steel with nothing to hide
The International Style was the first truly global architecture movement, and it still dominates city centres built between 1950 and 1975. Mies van der Rohe, Le Corbusier, and Walter Gropius argued that the structure should be expressed honestly: if a steel frame carries the building, the glass skin should say so rather than wrapping itself in ornament borrowed from another era. The result is a building with no cornice, no pediment, and no relief carving, only a flat skin of glass and metal repeated from ground to roof. Seagram Building, New York (1958) is the gold standard. If the building looks the same on all four sides and could theoretically be anywhere in the world, it is probably International Style.
Brutalism: the beauty argument for raw concrete
Le Corbusier's Unite d'Habitation in Marseille (1952) established the template: raw concrete left exactly as it came out of the timber formwork, every plank mark and bolt hole preserved as texture. The term comes from beton brut, French for raw concrete. Brutalism was the architecture of post-war optimism: universities, arts centres, public housing, and government ministries built with the belief that honest materials and geometric boldness were more democratic than historical ornament. London's National Theatre (1976) by Denys Lasdun is the most visited example. Three cues: the texture of the concrete surface shows the grain of the formwork timber; the building mass is composed of geometric volumes that project and recede; and the windows sit in deep recesses that cast strong shadows, making the facade three-dimensional.
Mid-Century Modern: the house that dissolved its own walls
Mid-Century Modern is the residential branch of Modernism, shaped by architects including Richard Neutra, Eero Saarinen, and Charles and Ray Eames. Where the International Style addressed offices and institutions, MCM addressed the single-family house: how to make a home that opened to its landscape rather than turning its back on it. The Farnsworth House in Illinois (1951) by Mies van der Rohe takes the principle to its logical conclusion: a glass box lifted just above the floodplain on eight white steel columns, with no wall between the interior and the surrounding trees. The three street-level cues are the low silhouette that hugs the ground, the wide overhanging eave that shades the glass, and the post-and-beam structure that makes every wall optional.
Art Deco vs Art Nouveau: the one-line test If the curves come from geometry (triangles, chevrons, zigzags), it is Art Deco. If the curves come from nature (vine stems, insect bodies, flower heads), it is Art Nouveau. The two styles are roughly twenty years apart and never overlap.
Neoclassical vs Beaux-Arts: the scale test Both use Greek columns. Beaux-Arts is always larger, always more ornate, and always more theatrical. If the building has allegorical statues above the column line and a grand staircase leading to the door, it is Beaux-Arts. If the building could plausibly be a small Greek temple, it is Neoclassical.
