Stop Building Concrete Coffins: Steal These Ancient Temple Hacks Before Our Cities Drown or Bake
Our cities are a mess. One monsoon and half the streets turn into rivers. Two months later the same streets become outdoor ovens. Water disappears into pipes nobody trusts, public spaces feel like afterthoughts, and every new building seems designed to fight the weather instead of living with it. Meanwhile, a thousand years ago, the people who built Indian temples were running multifunctional machines that handled water, heat, people and durability without a single generator or master-plan meeting. They weren’t just carving gods. They were doing town planning that still works better than a lot of what we pour concrete for today.
Water that actually works
Stepwells weren’t decorative holes in the ground. Chand Baori in Rajasthan, built around the 9th century, drops roughly 30 metres across 13 storeys with about 3,500 steps arranged in that inverted-pyramid geometry. When the monsoon came, it filled. When levels dropped, you simply walked further down. It stored local water, kept the lower levels several degrees cooler, and doubled as a shaded place people actually sat.
Rani ki Vav in Gujarat took the same idea and turned it into an upside-down temple of carved stone—UNESCO listed for a reason. Further south, temple tanks did the job at town scale. Madurai’s Golden Lotus Tank inside the Meenakshi complex still collects runoff from the entire premises through channels and clever pillar-pipes. It holds water through dry spells and sits ringed by corridors where people hang out.
These structures recharged aquifers, buffered floods and created microclimates while people used them. Modern version: neighbourhood-scale stepped tanks or stepwell-inspired plazas inside parks and housing clusters. Catch what falls on roofs and streets, let it store or percolate, and give people a cool edge instead of a fenced drain. Restored baolis already show groundwater responds when you stop treating every drop as a problem for some distant plant.
Public space that people actually use
The tanks and the mandapas around them weren’t reserved for priests. They were assembly halls, rest spots and festival grounds. In temple towns the complex sat at the centre—markets, residences and streets arranged so the civic heart was also the social one. Madurai still organises itself around the Meenakshi gopurams. Hampi’s ruins show tanks, canals and temples woven into the landscape rather than dropped on top of it.
Vastu texts, once you strip the packaging, encode practical climate rules: important openings face east or north-east for morning light and breeze; heavier mass sits on the hotter south and west; drainage moves away from buildings. Temple towns often grew in radial or grid patterns around that central complex, mixing uses within walking distance. The result was denser cores with identity instead of endless ribbon sprawl. Apply the same idea now: organise neighbourhoods around functional public cores—markets, schools, shaded halls, working water features—rather than treating every new layout as a blank slate for cars.
Buildings that don’t fight the weather
Jalis—those perforated screens—let light and air through while cutting glare and heat. High shikharas and open courtyards create stack ventilation so hot air rises and leaves. Thick local stone provides thermal mass. Structures like Brihadeeswarar at Thanjavur have stood through centuries and earthquakes partly because of interlocking stonework that didn’t rely on continuous cement joints. None of this needed electricity.
Modern public buildings and housing can use contemporary screens, proper orientation and mass instead of glass boxes that turn every afternoon into an energy bill. The temples simply refused to fight the climate.
Everything did more than one job. A tank stored water, cooled the surroundings and hosted people. A stepwell was infrastructure and social space at the same time. That systems thinking is the real lesson. Our current habit of separating the water department from the parks department from the building code guarantees the failures we keep seeing.
In a country staring down water stress and heat, ignoring this is expensive stupidity. Integrate working water bodies people can use, cool public spaces that invite lingering, and layouts that breathe, and the rest of the infrastructure gets easier. Ancient temple builders weren’t magicians. They were competent at making one move solve several problems. Our cities are already tanking. We can keep pretending concrete and pipes will save us, or we can step down into those old wells and lift the parts that still work.
