Station: [1] Entrance to the mine

Dear ladies and gentlemen, dear children,
first of all, I wish you a wonderful day. My name is Frederick.
I am your audio guide today and will accompany you through the mine.

Before we begin, here are a few instructions for use and safety:

Firstly: Safety helmets must be worn at all times in the mine. Not because you need to worry about falling rocks, but because the helmet is  to protect you from head injuries, as the rock is lower in some places. 

Secondly: Please pay attention to the path. The paths are made of concreteand do not have any steps. We will be walking uphill and downhill. In addition, the ground may be wet in some places. 

Thirdly: Please stay with the group at all times and do not leave the designated paths. It is easy to injure yourself on the loose rocks on the sides.

Fourthly: Please do not touch the gemstones. They will not only lose their brilliance but will also be damaged forever.

Fifthly: You may take photos during the tour.
