A visitor center for a once-polluted cave is getting a $3 million renovation. Officials at the American Cave and Karst Center hope to double the visitor intake at the Horse Cave Museum.
Peggy Nims of the American Cave Conservation Association said the renovations also include renovating historic buildings next to the cave.
The museum offers hands-on learning opportunities and an ecology tour for visitors. It draws about 20,000 visitors annually.
Horse Cave City Clerk Ann Matera said the museum's expansion is tied to the cleanup and comeback of the cave.
The cave was dormant to visitors for 50 years due to pollution from fertilizer, pesticides and sewage. A cleanup project allowed the cave to become accessible again in 1993.
