Mynydd Llwyn-gwern, also called Mynydd Llwyngwern, is a mountain in Snowdonia, Wales. It stands tall above two rivers, the Afon Dulas to the west and the Nant Ffrydlan to the east. The top of the mountain has some interesting low mounds. These are called pillow mounds.
This mountain is part of a group known as the Dyfi hills.
A Mountain with a Past: The Quarry
For many years, Mynydd Llwyn-gwern was home to a busy place. This was the Llwyngwern slate quarry. A quarry is a large pit dug into the ground. People dig there to get out useful rocks. This quarry was used to get slate. Slate is a type of rock used for things like roofs and blackboards.
The quarry started working in the 1820s. It kept going for a long time, until about 1950. Imagine all the slate that came out of that mountain!
From Quarry to Green Living
After the quarry closed, the site found a new purpose. In 1972, something exciting began there. It became a place for people to try out "green living." This means finding ways to live that are good for the planet.
This experiment grew into a famous place. It is now known as the Centre for Alternative Technology. This centre teaches people all about sustainable ways to live. They show how to use energy from nature.
Wind Power on the Summit
The Centre for Alternative Technology uses the mountain itself. They built a large wind turbine on the very top of Mynydd Llwyn-gwern. A wind turbine is like a giant fan. It uses the power of the wind to make electricity. This is a clean way to get energy. It does not harm the environment.
