On many Sundays, after the 10:00 a.m. mass, there is a guided tour open to those who are present. If you are coming to the Cathedral and would like to know if there is a tour scheduled that Sunday, call the Parish Office at 859-431-2060. Note, tours can be canceled with little notice depending upon the availabilty of a Docent to lead the tour.
