This barred tunnel was once a bustling entrance to the Star Mine, one of the most active coal mines in the area, providing a livelihood for many families. The rusted bars that now block the entrance are a stark reminder of the mine's past glory and the hard work that went into extracting coal from deep beneath the earth's surface.
