Chile wants a tunnel under the Strait of Magellan to link Tierra del Fuego with the continent. The project exists, the agreement with Argentina does not

Today, if a person wants to cross from Chile or Argentina to the island of Tierra del Fuego, they depend on ferries and barges. Normally, about 600 vehicles and around 2,000 people They cross the island every day. The extreme southern region of Patagonia is also a complicated area in meteorological terms, which leads to the suspension of maritime transport services every now and then. Hence, it makes all the sense in the world that they are considering building an underwater tunnel that connects both regions. The idea is to build an underpass of about 3.7 kilometers in the First Angostura, thus replacing ferry transportation. The project has existed on paper for a long timebut now it has just gained some political momentum. What exactly is proposed. The project would consist of an underwater road tunnel that connects Punta Delgada, in the continental zone, with Bahía Azul, on the Big Island of Tierra del Fuego. This section, known as First Angostura, is the point where the Strait of Magellan narrows to the maximum, making it the most technically reasonable place to attempt a work of these characteristics. Why is it resurfacing now? The project has been included since June 2025 in the Extreme Zones Development Plan 2025–2035 of the Magallanes Region. The governor of Magallanes, Jorge Flies, has been the main person responsible for restore some visibility to the initiative in recent weeks, according to some media reports. What the technicians say. Francisco Hernández, academic at the University of the Andes, counted to the Uruguayan edition of El País that the work is technically possible, but warns that it should not be seen “as a simple work.” The media also points out more difficulties than the length of the route, including the detailed study of the geology of the seabed, the water pressure, the currents or the seismic behavior of an area located very close to the mountain range. Depending on the results of these analyses, the project could be executed with a TBM-type tunnel boring machine or using conventional rock excavation techniques. According to account According to La Nación, Norwegian engineers have already reviewed the proposal in a preliminary phase and concluded that the conditions could be favorable. cHow much does it cost and who pays. The estimates oscillate between 500 and 1.5 billion dollars. As it is a binational project, Chile and Argentina would have to agree on the distribution of the investment, the management model and long-term maintenance guarantees. The media also points out that viability does not depend only on engineering, but on there being a firm agreement between both countries on who pays, under what conditions and with what operating scheme. What point is it really at? For the moment, the tunnel is nothing more than a proposal included in Chile’s planning. There is no official confirmation of the start of works, no definitive agreement between the two countries, nor guaranteed financing. The next step would be to complete the geotechnical and geophysical studies that allow the design, costs and security, evacuation and emergency systems to be refined. Until then, we will have to wait to find out if the project finally comes to fruition.

In the 16th century, Spain wanted to control the Strait of Magellan by founding a city. It became a cursed settlement

A coin is a coin. And a compass, a compass. What seems so obvious changes when we talk about the old (and ephemeral) city ​​of King Don Felipea Spanish settlement founded more than four centuries ago by Pedro Sarmiento de Gamboa on the northern shore of the Strait of Magellan. Its objective was to become a fortress that would reinforce the control of the Spanish Crown in a strategic maritime passage, but the mission became so complicated that the town ended up becoming a death trap for its settlers. Things went so badly that with the passage of time the citadel ended up being renamed ‘Port of Hunger’a name much more in line with what happened there in the 17th century, and its memory it faded in the mists of history. We had to wait until well into the 20th century so that the secrets of King Don Felipe would emerge from oblivion… and the earth. Now the archaeologists have found among its ruins a small piece of silver that in March 1584 Pedro Sarmiento de Gamboa himself deposited there during the founding ceremony of the town. In its day it was a simple currency (a real of eight) that was used for ritual purposes. In 2026 it has become something more: a compassa guide that will help researchers better understand the structure and location of the city of Rey Don Felipe, the cursed citadel in the Strait of Magellan that should never have existed. At the ends of the world Today the world lives pending what happens in the Strait of Hormuz. Almost five centuries ago the eyes of the Spanish Crown were directed towards another maritime strait with important strategic value: that of Magellana navigable strip located south of what is now Chile and that stands out as the natural connection between the Pacific and the Atlantic. Since Ferdinand Magellan crossed it for the first time, in the autumn 1520the pass became an object of desire for the Spanish Empire, especially after other expeditions managed to cross it successfully and the English entered the race for its control through late 1570s from the hand of the corsair Francis Drake. To guarantee Spain’s geopolitical plans and its exclusive control of the transoceanic passage, the authorities had an idea: found permanent settlements in the area. The mission fell to Pedro Sarmiento de Gamboaa hardworking sailor who, among other missions, had participated in a (frustrated) mission of the Viceroyalty of Peru to hunt down Drake. Sarmiento first undertook an expedition with two ships in the autumn of 1579 to reconnoiter the coastline of the strait and explore its coasts and, once back in Spain, in 1580 he played a decisive role in getting the Council of the Indies to decide to build citadels and fortifications in the transoceanic passage to America. The expedition left Sanlúcar at the end of September 1581 with a fleet of 23 boats and around 3,000 men, including sailors and future settlers. Despite his enormous ambition, the adventure started badly. And not only because of the differences between Sarmiento and Diego Flores de Valdeswho had been appointed captain general of the Strait Navy. Before even leaving Cádiz, a storm sank half a dozen ships and killed 800 men. What followed next was a journey marked by disagreements between Sarmiento and Valdés, illnesses, the inclemency of the ocean and storms that caused the expedition to lose ships, crew and supplies. After various incidents and vicissitudes, Sarmiento and his men arrived at the strait at the beginning of 1584 and founded a city that they named ‘Purification of Our Lady’. It didn’t work. The location and climate did not help, so Sarmiento looked for a new enclave, near Cape Vírgenes, and founded a settlement which he called ‘Name of Jesus’. Determined to continue with the mission, the sailor chose part of the 340 people he kept and looked for a third location to create another citadel. On this occasion he baptized it with a nod to the Habsburg court (King Don Felipe) and celebrated the founding ceremony in March 1584. We know that Sarmiento himself participated in the ritual. On March 25, he laid the first stone of the citadel church and, with it, in the foundations, buried a real of eight silver. As they explain from the Bernardo O’Higgins University of Santiago, it was “a symbolic gesture that marked the birth of the city.” If the ritual was intended to promote the settlement’s fortunes, it only half worked. It has served archaeologists of the 21st century, who have just found the coin “in place and position” described by Sarmiento in his writings and now, thanks to that clue, they will have an easier time interpreting a map of the 16th century in which the buildings of the town are represented. The one who certainly had no use for the currency was the colonists who settled in Rey Don Felipe city. Theirs was a tragic story from the beginning. a cursed city Ciudad Rey Don Felipe may have enjoyed a privileged location from a geopolitical and strategic point of view, but the truth is that it soon became hell for its settlers. And not only because the crew of the ill-fated (and diminished) Armada del Estrecho arrived in Magallanes at the limit of their strength. In ‘Port of Hunger. Beyond the legend’a work signed by the historian Soledad González and the archaeologist Simón Urbina, a key piece of information is provided: “On board the ships or on land they saw people die or desert. nine out of ten colleaguesfriends or family. As if that were not enough, after founding the Nombre de Jesús settlement, the crew divided into groups to expand towards the Santa Ana peninsula, precisely to establish Rey Don Felipe. Once there, and despite the fact that Sarmiento de Gamboa was quick to lay the foundations of the new citadel (both in a metaphorical and literal sense), things did not improve. The scene looked so bad … Read more
