A 120-Year-Old Denmark Lighthouse Rides Away From Coastal Erosion on Rollerblades

Beachgoers know all too well what happens when you plop down near the ocean during low tide—it creeps slowly closer until one enthusiastic wave soaks all your towels and escapes with your flip-flops. Luckily, you can to relocate your belongings farther inland, or simply check the tide tables before settling down to sunbathe.

For a 120-year-old Danish lighthouse, it’s not that simple. When Northern Denmark’s Rubjerg Knude lighthouse was built in 1899, there was more than 650 feet of land separating it from the coast. According to Condé Nast Traveler, that seemingly safe expanse of sand had eroded to fewer than 20 feet by the 2000s.

To rescue the 1000-ton landmark from imminent destruction, local mason Kjeld Pedersen approached the Danish government with an innovative proposition: Slide the lighthouse to safety on a pair of custom-sized rollerblades. Since a similar plan had succeeded in moving a gun repository in Skagen, a town about 45 miles from Rubjerg Knude, the government gave the green light (and 5 million kroner, or about $743,000) to Pedersen.

Last week, Pedersen and his team mounted Rubjerg Knude on a pair of roller blades attached to a track, and scooted the structure about 263 feet inland. It wasn’t exactly a rip-roaring ride—they moved it 0.001 mph. At that rate, the entire operation took almost 50 hours.

As one can imagine, Pedersen was a bit tired after such an epic undertaking.

“It’s been overwhelming for him,” Visit Denmark’s Nina Grandjean Gleerup told Condé Nast Traveler. “I think he’s told Denmark ‘Don’t use me anymore’ because of all the attention!”

Gleerup also explained that Pedersen’s humble diligence and creativity reflected the spirit of the neighboring fishing towns, Løken and Lønstrup, which are known for quaint coffee shops, galleries, and beautiful natural landscapes.

Starting to think a lighthouse would make the perfect beachfront getaway? While Rubjerg Knude itself isn’t open for overnight visitors, there are plenty of other lighthouses near the sea—book a stay in one here.

2020 World Monuments Watch: 25 Historic and Cultural Landmarks That Are At Risk

Whether it's due to their age, size, or ubiquity in pop culture, certain landmarks can feel invincible. But that's far from the case: Each year, some of the most famous places on Earth are faced with new threats, including war, urban development, and climate change. In an effort to boost awareness of these vulnerable sites, the World Monuments Fund (WMF) has released its biennial roundup of 25 historic and cultural monuments around the world that need protection.

To finalize entries for its 2020 World Monuments Watch, the WMF evaluated more than 250 nominations from various groups and individuals. The final list includes monuments and cultural sites from five continents. Some, like Bears Ears National Monument in Utah, are threatened by weakened conservation laws, while others—like Notre-Dame cathedral in Paris—have been damaged by recent disasters.

The WMF plans to partner with the local communities around each site on the list to develop specific conservation plans to help save these landmarks. In spring of 2020, the program's founding sponsor, American Express, will donate $1 million toward the initiatives of a select group of sites from the list. To see every place included in the 2020 World Monuments Watch, check out the list below.

Mapping Technology Reveals 'Lost Cities' on National Geographic

Imagine what Pompeii looked like before the lava hit, or Mayan pyramids before the jungle took over. In the past decade, scientists have been able to explore human settlements long since abandoned by using a new wave of accessible technology. Instead of needing an expensive plane and crew to fly aerial sensors, for example, explorers can mount them on cheaper drones and pilot them into previously unreachable areas. The resulting data can tell us more about the past, and the future, than ever before.

That’s the premise of Lost Cities with Albert Lin, a new TV series premiering on National Geographic on Sunday, October 20.

Lin, an engineer and National Geographic Explorer, uses cutting-edge tools to shed light on centuries-old cities in the most beautiful places on Earth. Ground-penetrating radar reveals buried structures without disturbing the landscape. A drone-mounted remote sensing method called LIDAR—short for "Light Detection and Ranging"—shoots lasers at objects to generate data, which Lin visualizes with 3D mapping software. The results suggest what the ruins probably looked like when they were new.

“It’s like a window into a world that we’ve never had before,” Lin tells Mental Floss. “It’s shooting millions of laser pulses per second through a distance of air. By digitally removing the top layer of everything above the ground—trees, brush, cacti—you’re washing away the past. All of the sudden you’re left with these fingerprints—experiments in how we organized ourselves through time.”

For the six-episode series, Lin and the expert storytelling team were dispatched to the South Pacific, the Middle East, the Andes, the Arctic, and other destinations. Lin explains that while most of the sites are known to archaeologists, they’ve never been so precisely mapped in three-dimensional detail.

In the first episode, Lin travels to Nan Madol, an enigmatic complex of temples and other structures on the Micronesian island of Pohnpei. With the help of local researchers and indigenous leaders, Lin and the team scan the ruins and digitally erase trees, water, and forest undergrowth to unveil the complex's former grandeur.

“Technology and innovation have always been that gateway to go beyond the threshold, and see what’s around the corner,” Lin says. “Seeing these worlds for the first time since they were left, it’s almost like reversing the burning of the library of Alexandria. We can take the synthesis of knowledge of all these watershed moments of our human journey, and imagine a better future.”

Lost Cities With Albert Lin premieres Sunday, October 20 at 10/9c and resumes on Monday, October 21 at 10/9c on National Geographic.
