Three mini tours of the former Galgate Mill have been held over the last two weeks.
The listed building is currently standing empty after plans to turn it into student accommodation were rejected by city councillors earlier this year.
Everyone visiting had some connection with the mill, and there were visitors from as far as the south of England as well as a couple from Canada.
Rosemin Hussain, whose husband Ayub is behind the plans to redevelop the mill as student accommodation, said: “The turnout was excellent with more than 100 people attending over three days.
“The general feeling was of disbelief of the condition of the mill, and people were left questioning why the planners would object.”
An appeal into the change of use for high quality student accommodation with leisure facilities, a cafe and a museum to be built has now begun.
