Lowell Catholic celebrated its 20th Anniversary last Spring.  It serves as the only Catholic high school in the city of Lowell.  Its foundation can be traced back to five Catholic high schools in Lowell: St. Patrick High School, Keith Academy, Keith Hall/Keith Catholic, St. Louis Academy and St. Joseph High School.

Established in 1989 as a result of the merger of Keith Catholic, St. Joseph High School and St. Louis Academy, the school was initially known as Greater Lowell Catholic High School.

The planned merger was to be implemented over a three-year period and the first years saw the school operate with two campuses divided by the Merrimack River. These two branches were St. Joseph Hall on Merrimack Street and St. Louis Hall on Boisvert Street. The Keith Hall/Keith Catholic building remained closed and underwent major renovations.

In September 1991, the school completed the final phase of the merger, combining the two branches into one when they moved into the newly renovated Keith Hall/Keith Catholic building. Originally built as an orphanage in 1912, the school now known as Lowell Catholic High School had a physical capacity of three hundred students with one building.

In the Spring of 2006, a major capital campaign and expansion project finally culminated in what is now known as the Bishop McNamara Complex.  The Lowell Catholic campus now consists of three buildings;  Keith Gymnasium, McNamara Hall (consisting of a state-of-the-art science lab, auditorium, media center and additional classrooms) and Main Hall (containing classrooms, the cafeteria and media center).  The new campus can now comfortably accommodate over 400 students.
