Don't know the difference between a plinth and a pilaster? You don’t need to be an expert to recognise a good building but understanding a little about architectural history and theory can make a walk around an unfamiliar city all the more rewarding.
Get to grips with the basics and see how many styles you can identify while on the road with our simple guide.
Era: 850 BC to 476 AD
The mother of all architectural styles, the elegant proportions and stately poise of classical architecture sired a legion of later revivals. The grand temples and civic structures of ancient Greece and Rome followed strict rules known as the 'orders' of architecture. The three most important are Doric, Ionic and Corinthian; all easily recognisable from their capitals (the decorative bit at the top of the columns).
How to spot it: Doric: plain capitals. Ionic: scroll-like capitals. Corinthian: elaborate capitals with carved acanthus leaves.
Where to find it: the Colosseum or Pantheon in Rome; the Acropolis, Athens.
With glittering mosaics and more domes than a field full of mole hills, Byzantine architecture was built to impress. Walking into a lavishly decorated basilica with high domed ceilings and a blanket of gold ornamentation, worshipers would have been under no illusions about the power and wealth of the emperors.
The heavyweight of medieval architecture, Romanesque (called Norman in the UK) buildings were big, brawny and simple. A lack of technical know-how meant thick walls, massive columns and rounded arches were necessities while windows were small, vaults were built like barrels and decoration was confined to lozenges, chevrons or zigzags.
Era: 12th-16th centuries
The lovechild of improved building techniques and European prosperity, the Gothic style spawned buildings that were taller, lighter and brighter than ever before. Embraced by the church and state, the new style quickly swept across Europe. The key element is the pointed arch but the strength of the Gothic revival from the mid-18th to mid-20th century means that many you see will be much later in date.
Era: 14th-17th century Europe
It's revision time. Remember those classical orders of architecture? They're back in fashion. As classical philosophy and ideas on arts and literature were revived, architects too returned to the proportion and symmetry of classical Greek structures but embellished them in lavish ways.
Baroque and rococo
With all the pomp and pomposity of a powdered wig, baroque architecture was a sugary confection of extravagant ornamentation. The baroque period added more elaborate decorative features to buildings than ever before and by the late 18th-century had become the totally theatrical rococo, where every surface was awash with flamboyant flourishes.
Era: mid-18th century Europe
Repulsed by the sickly-sweet excesses of the rococo era, prim and proper neoclassicism returned to ancient Greece and Rome for inspiration. Unlike during the Renaissance, it played strictly by the rules in a sometimes severe reincarnation of the original styles.
Curvy, leafy and forever associated with Paris thanks to its iconic Metro entrances, art nouveau was a short-lived movement that saw weaving, plant-like designs and flowing natural forms permeate everything from furniture design to architecture.
How to spot it: flowing lines, organic forms and decorative plant-like designs.
Where to find it: Musée Horta, Brussels; Paris Metro entrances; Lavirotte Building, Paris.
All the glamour and sophistication of the roaring 20s is reflected in art deco architecture and its expensive materials and clean, geometric design. Flappers danced in jazz clubs, the great Gatsbys threw wild parties and architects cleverly used minimal decoration to create a sense of unbridled luxury.
How to spot it: use of chrome, geometric motifs and strong colours.
Where to find it: Chrysler Building; Empire State Building; Miami Beach; Napier, New Zealand.
Era: early 20th century to 1980s
Austere, minimalist and unrepentantly plain, modernism insisted design should be dictated by function. Rectangular and cubist shapes, reinforced concrete, open-plan design, large windows and a lack of ornamentation are its hallmarks.
The architectural equivalent of wearing your clothes inside out, high-tech architecture gleefully embraced new technology and materials and showed it all off on the outside. Inside, these buildings had flexible layouts with moveable room divisions.
Era: 1960s to present
Experimental, controversial and playful, postmodernism replaced the puritanical principles of modernism with fun, irony and bright colours. Anything goes in this movement making it hard to recognise, but whimsical references to classical architecture were common and frequently provoked scorn.
Era: 1960s to present
Wilder than a Hollywood sci-fi set department, neo-futurism blends the latest technologies with brilliant minds and unbridled creativity, pushing materials and concepts beyond all previous boundaries. Buildings bend and twist in mysterious ways, lean at impossible angles and sweep along in undulating curves.
Era: 1960s to present
Trippy, mind-bending architecture that looks like it may just have begun to melt, deconstructivism's weird free-form shapes, sloping walls and distorted surfaces are instantly recognisable. Anarchic and disorderly yet meticulously planned, a visit to one of these buildings can be a perplexing experience.
How to spot it: distorted, flowing shapes, often in reflective materials.
Where to find it: Guggenheim, Bilbao; Der Neue Zollhof, Düsseldorf; The Museum of Pop Culture, Seattle; Jewish Museum, Berlin.
