As the construction work was so slow — at some 3–4 meters a week — it was decided, in 1827, to allow public tours of the tunnel. The general public were charged 1 shilling per person; viewing times were from Monday to Saturday seven in the morning till eight in the evening. The scheme proved to be popular and an estimated 600–800 visitors per day came to marvel at its construction.
