Explore Blaenavon UNESCO World Heritage Site and the Big Pit National Coal Museum

Nestled in the heart of South Wales, Blaenavon is a part of the industrial revolution that shaped much of the modern world. Declared a UNESCO World Heritage Site in 2000, the town and its surrounding landscape offer an insight into the coal-mining and iron-making industries that powered Britain during the 18th and 19th centuries. One of the most iconic landmarks in Blaenavon is the Big Pit, a former coal mine that has since been transformed into a museum.

What makes Blaenavon Industrial Landscape a UNESCO World Heritage Site?

Blaenavon’s place in history is not just about its scenic beauty; it’s about the role it played in the development of coal mining and the iron industry. The town grew rapidly in the late 18th century due to its coal deposits and the ironworks that followed. These industries were integral to the Welsh economy and became the engine of the industrial revolution.

Blaenavon was one of the first places to experience the large-scale production of iron, making it a crucial player in shaping the world as we know it today. The town’s mining heritage and its impact on the development of modern industry were key factors in its recognition as a UNESCO World Heritage Site.

Exploring Big Pit: A Historic Coal Mine

The History of Big Pit

The Big Pit National Coal Museum is perhaps the most famous attraction in Blaenavon. Once a thriving coal mine, it operated for nearly 100 years before being closed in 1980. It’s now a museum dedicated to preserving the legacy of coal mining in Wales.

The underground tour is the highlight of any visit, offering a unique chance to descend into the mine and experience what life was like for the miners who worked here. Led by former miners, the tour takes you deep underground, where the sights and sounds of the past come to life. As you walk through the tunnels, it’s impossible not to feel a sense of awe for the miners who laboured in these dark, damp conditions day in and day out.

Above Ground: The Museum Experience

Above ground, the museum houses a wealth of exhibits detailing the history of the mine, the technology used, and the daily lives of the miners. The displays explore the tools and machinery used in the mining process, the hardships faced by workers, and the cultural impact of coal mining in the region. The museum is a fitting tribute to the generations of men and women who worked in the mines and it offers a powerful reminder of the importance of this industry to Wales’ economy and identity.

The Welsh Pit Ponies: Unsung Heroes of the Mining Industry

No discussion of the Big Pit would be complete without acknowledging the vital role played by the Welsh pit ponies. These small, sturdy horses were an integral part of the coal mining operations in Wales, including at the Big Pit. They worked in the dark, damp tunnels, hauling coal and equipment through narrow, low-ceilinged passageways. These ponies were essential to the mining process, allowing miners to transport coal from deeper underground areas to the surface.

Life for the pit ponies was harsh. They were often kept underground for long periods, with minimal time spent outside. Their diet consisted mainly of hay, oats, and water, and they were worked tirelessly for up to 12 hours a day. Despite the challenging conditions, these ponies developed a remarkable bond with their handlers, who knew them well.

Today, you can learn more about the Welsh pit ponies at the Big Pit Museum, where the history of these hard-working animals is celebrated. The legacy of the Welsh pit ponies is a poignant reminder of the many overlooked aspects of mining life, and they remain an important part of the region’s industrial heritage.

Things to Do in Blaenavon and Surrounding Areas

While Blaenavon’s industrial past is at the forefront of the town’s story, there’s much more to explore in the area. The Blaenavon Ironworks, located just a short walk from the town centre, is another key historical site.

Once one of the largest ironworks in Wales, it played a pivotal role in development during the Industrial Revolution. It opened in 1789, and the museum includes 18th- and 19th-century furnaces, casting houses, calcining kilns, workers’ cottages, and the iconic water balance.

The town has a number of old buildings, including St. Peter’s Church, built by the ironmasters in 1804, the Blaenavon Workmen’s Hall, built in 1894, and St. Peter’s School, built by the ironmaster’s sister in 1816 and is now the World Heritage Visitors Centre.

If steam trains are more your thing, then it is possible to take a ride from Coed Avon to Whistle Inn Halt. The small Blaenavon Heritage Steam Railway runs through the summer and special occasions over the winter.
