Harry Potter Fans Got a £430 Million Power Cable Moved to Save Dobby's 'Grave'

A £430 million undersea power cable between the UK and Ireland had to be moved after hundreds of Harry Potter fans complained that its route would go through a makeshift memorial on a Welsh beach — the spot where the character Dobby the house-elf was buried in the film Harry Potter and the Deathly Hallows (The Guardian).
The cable is called the Greenlink interconnector. It runs 125 miles along the seabed and carries renewable electricity — power generated by solar panels and wind turbines — from the UK to Ireland. It is like a giant extension cord laid across the ocean floor so the two countries can share clean energy.
Greenlink's project manager, Simon Ludlam, said in a BBC interview that the original cable route would pass underground through the Dobby memorial on Freshwater West beach in Pembrokeshire, Wales. After the interview, he told the Energy Revolution podcast that hundreds of fans called to object. Greenlink then hired planners to find a new route that would avoid the memorial (The Guardian; Metro; The Telegraph).
The new route avoided Dobby's 'grave' but created a different problem. It ran close to real ancient remains from the Bronze Age — a period thousands of years ago — including burial urns that held human ashes (The Guardian).
Freshwater West beach is owned by the National Trust, a conservation charity. The Trust has a difficult relationship with the Dobby memorial. Fans keep leaving stones marked "Here Lies Dobby" on the beach, even though the Trust has asked them to stop because the area is environmentally fragile. In October 2022, National Trust Cymru (the Trust's Welsh branch) put forward plans for "a sustainable future for Freshwater West" (Wales247). After asking the public for input, the Trust decided in November 2022 that the memorial could stay "for now" (ITV Wales; Nation.Cymru).
The Greenlink cable is part of a wider network linking the British and Irish electricity grids. That network has drawn growing attention for security reasons. In March 2026, the UK and Irish governments announced practice exercises to test how ready they are to deal with damage to undersea cables (Reuters; Global News).
The broader context here is one of competing claims on the same piece of land. A memorial to a fictional character, kept alive by fans against the landowner's wishes, had enough influence to change the route of a £430 million energy project. But moving the cable to protect that memorial brought it near real ancient burial sites that are thousands of years old. The situation shows how building large energy projects has become more complicated: environmental rules, protections for historical sites, and public opinion can each force expensive changes at any stage.
There is also a security angle. The practice exercises announced in March 2026 show that both governments are worried about undersea cables being sabotaged or accidentally damaged. A cable whose land route was shifted because of a fan campaign is now part of a corridor that both governments want to protect. The irony is built into the situation: a project meant to carry clean energy between two island nations is routed around constraints ranging from Bronze Age archaeology to modern pop culture, while also sitting inside a security framework shaped by today's concerns about undersea infrastructure.
For anyone building similar projects, the lesson from Greenlink is that public opinion can come from unexpected places. Organized fan communities tied to filming locations can make enough noise to force changes that project managers did not see coming. Planning ahead by mapping out all the people and groups who might object could save time and money later — though the exact mix of a famous film location, a fragile natural site, and ancient burial grounds on the same stretch of Welsh coast is unlikely to happen again in quite the same way.
