Excavation to an area rich in slate deposits, which is still being mined today. The slate was mined here in the 19th century and most of the mines were closed during World War II. The area runs a nature trail, which will inform tourists about the area and the history of the mining. But we decided to explore the area from underground. Some underground rooms are truly dominant and reach truly incredible proportions. I do not have any pictures, but I did a video at least.
