🇰🇷 Seoul: The Speed City

What you’ll learn

1. Ppalli-PpalliEstablish ppalli-ppalli as the course's through-line and state the argument: Seoul's triumphs and its catastrophes are the same decision seen twice.'Ppalli-ppalli' — quickly, quickly — is treated by Koreans themselves as the national temperament, and this course treats it as an argument rather than a quirk. In 1953 Seoul was rubble and South Korea's income per head was on the order of a hundred dollars a year, below North Korea's; today Seoul holds about 9.6 million people at the centre of a capital region of some 26 million, roughly half the national population on about a tenth of the land, at Western European income levels. The course's claim is that the speed which achieved this is the same speed that produced the disasters, and it follows that one choice through seventy years rather than touring the city's sights.
2. Why Here: The River and the RingExplain Seoul's site — the mountain-ringed basin and the Han — the pungsu logic of baesan imsu that placed the capital in 1394, and the fact that the city sits ~50 km from the DMZ.Seoul sits in a basin ringed by mountains, with Bukhansan rising over 800 m to the north and the Han River running through, giving a pre-modern capital a defensive wall it did not have to build and a river that served as both moat and supply highway in a country roughly 70% mountain. King Taejo moved his capital here in 1394 following pungsu and specifically baesan imsu — mountain at the back, water in front — and placed Gyeongbokgung at the basin's northern edge facing south, which is why Gwanghwamun still opens onto a boulevard running dead south. Seoul also lies about 50 km from the DMZ, within conventional artillery range, a condition under which every structure in this course was built.
3. Five Hundred Years, Mostly RebuiltUse Gyeongbokgung's cycle of destruction and rebuilding to show that Seoul's 'old' is largely reconstruction — and explain why that is continuity rather than fakery.Gyeongbokgung was built in 1395, burned in the Imjin War of the 1590s and left a ruin for some 270 years, rebuilt in the 1860s under the Heungseon Daewongun, then largely dismantled under Japanese colonial rule, with the colonial Government-General building erected across its axis in 1926; South Korea demolished that building in 1995 and reconstruction continues today. The instinct to feel cheated by reconstruction imports a European assumption that authenticity lives in original material, which does not fit an East Asian wooden tradition where a building is a form maintained across time rather than a relic preserved from it. Rebuilding was also a political statement about who the country belongs to — and Seoul made it the way it makes everything: by building, fast.
4. Rubble, and the DecisionSet the 1953 baseline of a destroyed city and show that the 'Miracle on the Han' was a method — speed imposed from the top — with the Gyeongbu Expressway as its emblem.Seoul changed hands four times between June 1950 and March 1951 and was largely destroyed by the 1953 armistice, with contemporary observers writing the country off entirely. What followed is usually told as economics — export-led industrialisation, the chaebol, state-controlled credit under Park Chung-hee from 1961 — but the method was speed imposed from above, and its emblem is the 428 km Gyeongbu Expressway from Seoul to Busan, built in two and a half years from 1968 to 1970 by working around the clock, cutting corners on surveys, and accepting that men would die; dozens did, and there is a memorial. Meanwhile Seoul grew from roughly 1.5 million in the early 1950s past 10 million by 1990, which had to be housed fast, at scale, and identically.
5. The Apartment RepublicExplain the danji as a replicable unit of settlement and teach the jeonse mechanism properly — including what happens when its assumptions break.Seoul's answer to housing millions fast was the danji: not a building but a replicable unit of settlement, arriving complete with parking, playgrounds, kindergarten and shops, built in one operation and numbered in huge digits — and over 60% of South Korean homes are now apartments, which is why Valérie Gelézeau's 'apartment republic' stuck. Underneath it sits jeonse, a contract in which the tenant pays a lump sum of typically 50–80% of the property's value, lives there with no monthly rent, and gets it all back: the deposit is an interest-free loan the landlord invests, so the return on the money is the rent. It depended on high interest rates and permanently rising prices, and when Korean property prices fell after 2022 landlords could not repay deposits that were often a tenant's entire net worth and frequently borrowed — producing the jeonse fraud crisis, government guarantees and prosecutions, and a shift toward monthly rent.
6. The Bill for SpeedPresent the Seongsu Bridge and Sampoong Department Store collapses factually and soberly, and show that every link in the Sampoong chain is the same speed instinct that built the expressway.On 31 October 1994 a span of the Seongsu Bridge fell into the Han during rush hour, killing 32 people, with defective welding, skipped inspections and deferred maintenance found on a bridge built fast in 1979. On 29 June 1995 the Sampoong Department Store collapsed into its own basement in about twenty seconds, killing 502 people — the deadliest peacetime building collapse of the modern era — after the owner converted an office block to a store by removing support columns, fired the contractor who refused, added an unplanned fifth floor of heated-floor restaurants, had rooftop AC units dragged across the slab, and then, warned of cracks on the morning itself, evacuated the executives and kept the store open. Every link is ppalli-ppalli applied where it had nowhere to hide; Korea responded with a serious overhaul of building codes, inspection and enforcement, and the 2014 Sewol disaster reopened the argument because the pattern was instantly recognisable.
7. Buying It BackUse Cheonggyecheon and the subway to show a city spending money to undo its own reflex — including the traffic evaporation finding and the fair criticisms of the project.Cheonggyecheon was covered with concrete through the 1950s–60s and topped with an elevated four-lane expressway in 1976, which by 2000 was decaying and expensive to repair; instead of fixing it, Seoul demolished it in 2003–05 and restored about 11 km of stream as a sunken linear park at a cost on the order of 900 billion won. The traffic did not materialise as feared — it redistributed onto other routes, the simultaneously overhauled bus system and the subway, and some simply evaporated, making the project one of the most-cited demonstrations that traffic is partly a function of road space provided. The criticisms are also fair: the water is pumped in from the Han and groundwater rather than flowing naturally, and vendors were displaced as property values rose. Seoul's subway, opened in 1974, is now among the largest and busiest on earth, with platform screen doors, signal in every tunnel and integrated fares — the same impatience, aimed at infrastructure that carries people.
8. Gangnam, and the Geography of MoneyExplain Gangnam as a deliberate state construction — land readjustment, bridges, relocated offices and above all relocated elite schools — and decode 'Gangnam Style'.Gangnam, south of the Han, was pear orchards and rice paddies in 1970; Seoul had run out of room in the basin and had a security reason to spread away from the northern hills, so the state built a second city across the river using land readjustment, new bridges, and the relocation of the express bus terminal and government offices. The decisive tool was moving the schools: from the mid-1970s Seoul's most prestigious high schools were relocated to Gangnam and the hakgun 8 school district drawn around them, which in a society where university entrance largely determines a life made a Gangnam address a strategy rather than a luxury — property prices and the hagwon cram-school industry of Daechi-dong followed. 'Gangnam Style' was heard outside Korea as a novelty track and inside Korea as satire about a man performing the manners of a district the state deliberately manufactured as the place where success lives.
9. Speed as an ExportShow Hallyu as industrial policy born from the 1997 crisis, place the trainee system in the course's pattern, and land the through-line on the fertility rate — the one bill that cannot be paid quickly.The Korean Wave began as a response to the 1997 Asian financial crisis and the IMF bailout: the government concluded Korea was over-dependent on heavy manufacturing, built culture ministries, funding bodies and later the Korea Creative Content Agency, and in 1998 lifted the ban on Japanese cultural imports — one of the few cases of a state deliberately manufacturing a cultural export sector and succeeding. The trainee system recruits children into years of drilling under contract in company dormitories, with most never debuting: extraordinary output at a price paid by people whose names are never learned, which forced Korea's Fair Trade Commission to intervene over 'slave contracts'. The final bill is demographic: South Korea's total fertility rate was about 0.75 in 2024 and Seoul's about 0.58 — against the 2.1 needed for a stable population — driven by housing costs, an education arms race and working hours capped only in 2018 at 52 a week, and it is the first problem the city has faced that cannot be solved ppalli-ppalli.
