How a Lighthouse Changed a Border

How a lighthouse changed a border

Did you know that a small lighthouse once forced Sweden and Finland to change their border?


Märket is a tiny, rocky island located in the northern Baltic Sea, shared by Sweden and Finland. The island, which measures only about 300 meters long, has a fascinating history—especially when it comes to borders. In 1885, Finland built a lighthouse on the island to help guide ships through the treacherous waters of the archipelago. However, there was one significant problem: the lighthouse was accidentally constructed on the Swedish side of the island.


This unintentional mistake set off a series of diplomatic negotiations. In 1985, nearly 100 years later, Sweden and Finland agreed to resolve the situation by redrawing their border, but instead of a straight line across the island, the new boundary zigzagged around the lighthouse, ensuring that the structure remained under Finnish control while preventing Sweden from losing any land.


What makes this case particularly intriguing is that Märket is one of the few places in the world where a border was altered specifically due to the location of a building. The unique decision to modify the border just for the lighthouse is a rare example of countries compromising over an insignificant geographical feature to maintain diplomatic relations.


Märket’s lighthouse continues to be a symbol of cooperation between Sweden and Finland, a reminder of how even the smallest of structures can lead to significant changes in international boundaries. The island now serves as a shared symbol of the two nations’ long history of peaceful coexistence.


So, do you think the countries made the right decision to change the border just for a lighthouse? Would you have handled it the same way? Let us know your thoughts in the comments below!

Exploring Calakmul: The ancient mayan city hidden in the heart of the Mexican jungle

Nestled deep within the dense jungles of the Mexican state of Campeche lies Calakmul, one of the largest and most powerful ancient Mayan cities ever discovered. This remote and awe-inspiring archaeological site offers a glimpse into the rich history and cultural heritage of the Mayan civilization. With its towering pyramids, expansive plazas, and intricate hieroglyphics, Calakmul is a testament to the ingenuity and sophistication of the Mayan people.

A brief hstory of Calakmul

Calakmul, whose name means “City of the Two Adjacent Pyramids,” was once a thriving metropolis at the heart of the Mayan world. It was one of the most influential cities during the Classic period (250-900 AD), rivaling the famous Tikal in Guatemala. The city served as a major political and economic center, with a population that likely exceeded 50,000 at its peak. Its strategic location allowed it to control vast trade networks and wield significant influence over neighboring regions.

The city was first discovered in 1931 by American biologist Cyrus L. Lundell, who stumbled upon the ruins while conducting a botanical expedition. Since then, extensive excavations have revealed a wealth of information about Calakmul’s history, culture, and architecture. In 2002, the site was declared a UNESCO World Heritage Site, recognizing its outstanding universal value and ensuring its preservation for future generations.

Architectural marvels of Calakmul

One of the most striking features of Calakmul is its monumental architecture. The city is home to over 6,500 structures, including towering pyramids, grand palaces, and sprawling plazas. The two largest pyramids, known as Structure I and Structure II, dominate the skyline and offer breathtaking views of the surrounding jungle.

  • Structure II: Standing at 45 meters (148 feet) tall, Structure II is the tallest and most impressive pyramid in Calakmul. It consists of multiple tiers, each adorned with intricate carvings and hieroglyphics that tell the story of the city’s rulers and their achievements. Climbing to the top of Structure II provides a panoramic view of the dense jungle canopy, a sight that is both humbling and awe-inspiring.
  • Structure I: Slightly smaller than Structure II but no less significant, Structure I is another remarkable example of Mayan engineering and artistry. Its steep steps and well-preserved carvings provide valuable insights into the religious and ceremonial practices of the ancient Mayans.

The rich cultural heritage of Calakmul

Beyond its architectural grandeur, Calakmul is also renowned for its rich cultural heritage. The city’s numerous stelae—tall, sculpted stone slabs—are adorned with detailed hieroglyphics that chronicle the lives of its rulers, battles, and alliances. These inscriptions have been invaluable in piecing together the history of the Mayan civilization and understanding the complex social and political dynamics of the time.

Calakmul was also a center for artistic and intellectual activity. The city produced exquisite pottery, intricate jade carvings, and elaborate murals that depict scenes from daily life, religious rituals, and mythological stories. These artifacts provide a fascinating glimpse into the creativity and sophistication of the Mayan people.

Preserving Calakmul for future generations

Today, Calakmul is a protected archaeological site, with ongoing efforts to preserve its structures and artifacts. The remote location of the city has helped shield it from the impacts of modern development, allowing visitors to experience the site in a relatively untouched state. However, the preservation of Calakmul is an ongoing challenge, requiring the dedication and collaboration of archaeologists, conservationists, and local communities.

For those who venture into the heart of the Mexican jungle to explore Calakmul, the journey is well worth the effort. Walking among the ancient ruins, surrounded by the sounds of the jungle and the echoes of a bygone era, is a profoundly moving experience. Calakmul stands as a testament to the enduring legacy of the Mayan civilization and a reminder of the incredible achievements of our ancestors.

Visiting Calakmul

Reaching Calakmul is an adventure in itself, involving a journey through dense jungle and often guided tours to navigate the site. The nearest town, Xpujil, serves as a base for visitors and offers accommodations and amenities. From there, it’s a 60-kilometer drive through the Calakmul Biosphere Reserve to reach the site.

For those interested in history, archaeology, and the natural beauty of the Mexican jungle, a visit to Calakmul is a must. It’s an opportunity to step back in time and immerse oneself in the grandeur of an ancient civilization, to walk in the footsteps of the Mayans, and to marvel at the architectural and cultural achievements of one of the world’s greatest ancient cities.

In conclusion, Calakmul is not just a hidden gem of the Mayan world; it’s a treasure trove of history and culture waiting to be discovered. Its remote location and well-preserved ruins offer a unique and authentic glimpse into the past, making it a must-visit destination for anyone interested in the rich tapestry of human history.
