In North Korea, visitors usually see only carefully chosen places.
One of them is the Pyongyang metro, among the deepest in the world. For years, foreigners were allowed to travel only between two stations, including Yonggwang Station, designed to show the system at its finest.
Opened in 1987, the station features marble and granite walls, rows of columns, and bright flower-shaped chandeliers. Large murals along the platform depict Pyongyang in spring, and a mosaic shows Lake Chon on Mount Paektu.
P.S. Commuting at its fanciest.

In Japan, crowded trains are almost a legend of their own. At peak hours, staff were even hired to gently push passengers into already packed carriages.
In the 1970s, trains on the Keihan Electric Railway line reached up to 250% capacity. Adding more trains was not an option, so engineers had to rethink the design itself.
The result was the Keihan 5000 series. Each carriage had five doors per side instead of three. To make space, seats could be lifted up above the doors during rush hour, then lowered again when the crowds cleared.
These trains are now being retired as modern platform systems are introduced.
P.S. Rush hour: now you see the seat, now you donβt.

Istanbul is one of the few cities that sits on two continents, Europe and Asia, divided by the Bosphorus. Today, they are connected not just by bridges, but by the Marmaray rail line running beneath the water.
The project was built to ease constant traffic pressure. Roads and ferries could no longer keep up, so the solution went underground.
The tunnel runs about 60 meters below the seabed and stretches for nearly 1.5 km underwater. Built in sealed sections and designed for earthquakes, it can handle extreme conditions.
A train now crosses between continents in under four minutes.
P.S. Two continents. One stop.

Deep inside New Athos Cave in Abkhazia, thereβs a small underground railway that takes visitors through the mountain.
Opened in 1975, the line runs about 1.3 km with a narrow 914 mm gauge. It connects three stations: Entrance Gate, Anakopia Hall, and Apsny Hall. Trains move at up to 30 km/h, taking passengers deep underground before bringing them back to the entrance.
One detail stands out. The driverβs controls are installed only at one end of the train, so on the return trip the train moves forward but the driver is effectively facing the rear, with no direct view of the track ahead.
P.S. Exploring caves, minus the crawling.

The Stockholm Metro is often called the worldβs longest art gallery, and itβs easy to see why.
More than 90 of its stations are designed as immersive spaces, with exposed rock walls, bold colors, and large-scale artworks. Instead of hiding the tunnels, the system turns them into part of the experience.
Opened in 1950, the metro gradually evolved into a citywide art project. Different artists were invited to design stations, each with its own theme, from political messages to abstract forms. No two stops feel the same.
Today, it moves hundreds of thousands of passengers daily, turning an ordinary commute into something unexpected.
P.S. The only place where missing your stop feels justified.

The Millau Viaduct stretches across the Tarn Valley in southern France, so high that on some days it almost disappears into the clouds.
Opened in 2004, it holds the record as the tallest bridge in the world. The highest point reaches 343 meters, making it taller than the Eiffel Tower. It was built to bypass the slow drive through the valley and keep traffic moving.
What stands out is how light it feels. The piers are thin, the deck is narrow, and from a distance the whole structure looks almost unreal.
P.S. Ever wanted to take a drive through the sky?

Energy islands are large artificial platforms built at sea to collect, store, and distribute renewable electricity. Instead of connecting single wind farms directly to shore, they act as central hubs for multiple energy sources.
Key examples include:
- Denmarkβs North Sea Energy Island, designed to integrate up to 10 GW of offshore wind.
- Belgiumβs Princess Elisabeth Island, a planned hub for offshore wind connections and interconnectors.
These platforms also create space for future hydrogen production and large-scale energy storage, turning open sea into part of the power network.
P.S. Less vacation, more voltage.

The yakhchal is one of the most practical inventions of ancient Persia, designed to store ice and keep food cold in desert climates without electricity. Built as tall, dome-shaped structures with thick mud-brick walls, they relied on insulation, evaporative cooling, and underground storage.
In winter, ice was collected from nearby mountains or formed in shallow pools during cold nights, then stored in deep pits below ground. The shape helped trap cold air, while warmer air rose and escaped through openings at the top.
Some yakhchals were paired with windcatchers to improve airflow and cooling efficiency, allowing ice to last through long, hot summers in cities like Yazd.
P.S. Cooling, version 1.0. Still works.

The Akashi Kaikyo Bridge connects Kobe with Awaji Island and holds the record for the longest central span in the world.
Opened in 1998, it stretches nearly 4 kilometers, with a main span of 1,991 meters. The bridge was designed to handle some of the toughest conditions on Earth. Strong ocean currents, typhoons, and frequent earthquakes all had to be factored in.
During construction, the Great Hanshin Earthquake shifted the towers apart by almost a meter, forcing engineers to adjust the design in real time.
Despite that, the structure remained intact. Flexibility, not rigidity, is what keeps it standing.
P.S. Designed with trust issues.

Yuyuan Garden Station on Line 14 sits right under one of the oldest parts of Shanghai, near the City God Temple and the Bund.
It opened in 2021 and is the deepest station in the city.
The ceiling is what you notice first. It moves in soft, continuous waves, a quiet nod to the Huangpu River above. The curves also echo traditional rooflines, but in a very subtle way.
Line 14 operates without drivers and is designed for continuous, high-frequency movement across the city. It connects major districts with precise timing and a system that relies heavily on automation rather than manual control.
P.S. Old district, new tech.

The Qinghai-Tibet Railway is often called the highest railway in the world.
It runs from Xining in Qinghai Province to Lhasa, crossing about 1,956 kilometers of mountains.
The highest point is Tanggula Station, at 5,068 meters above sea level. At this altitude, temperatures can drop to around -40Β°C, and the air is noticeably thinner.
To keep passengers safe, trains are pressurized and equipped with onboard oxygen systems.
Building the line was a major engineering challenge. Workers had to stabilize frozen soil, manage landslides, and deal with extreme cold, all while minimizing damage to the fragile Tibetan Plateau ecosystem.
P.S. Where altitude sets the rules.

Set within a dense coastal rainforest near Vancouver, the Capilano Suspension Bridge is one of the areaβs most visited landmarks.
It stretches 137 meters across the Capilano River, about 70 meters above the canyon floor. First built in 1889 by engineer George Grant Mackay as a rope-and-plank crossing, it has been rebuilt several times into the steel suspension bridge seen today.
The structure moves slightly underfoot. That movement is intentional, allowing it to respond to wind and shifting weight.
Now part of a larger park with canopy walkways and cliffside paths, it turns a short crossing into a full immersion in the landscape.
P.S. Not rigid, just well-adjusted.

The Three Gorges Dam is one of the largest hydroelectric power stations ever built.
It sits on the Yangtze River in Hubei Province and stretches across the valley for about 2.3 kilometers. The structure rises around 180 meters and holds back a reservoir that extends far upstream.
Construction took more than a decade, with full operation beginning in 2012. Building it meant relocating entire towns and reshaping parts of the river system itself.
The dam produces large amounts of electricity, supplying regional grids and reducing reliance on coal in several provinces.
P.S. Same water, better management.

Two residential towers in Milan, known as the Bosco Verticale, rethink what high-rise living can look like.
Completed in 2014, the two towers are 80 and 112 meters tall and are covered with more than 900 trees, along with thousands of shrubs and plants. Instead of a typical facade, the buildings use vegetation as a living outer layer.
The project was designed by architect Stefano Boeri, who focused on bringing biodiversity into dense urban environments rather than separating nature from the city.
The greenery helps reduce heat, filter air, and create a more stable microclimate.
P.S. Landscaping, just with better views.
