Old Nicolet High School

The Old Nicolet High School is a historic school located in De Pere, Wisconsin, USA.

History
The building was a public high school until 1958. That year, it was purchased by the Norbertines and it was reopened as the Catholic boys' school Abbot Pennings High School in 1959. In 1990, the building was bought by the nearby Norbertine institution St. Norbert College and has since been used for classrooms and offices. Abbot Pennings High School was closed and consolidated with two other local single-sex Catholic high schools to form the coeducational Notre Dame Academy.

The building was added to the State and the National Register of Historic Places in 2015. It was listed on the National Register as Nicolet High School.
