Linton Hall School is a Catholic coeducational day-school occupying a 120‑acre campus in Bristow, Virginia, in Prince William County about 60 km (37 mi) west of Washington, D.C.

[3] As enrollment increased, the monastery building lacked adequate space for housing the academic and residential programs.

In 1946, the first floor of the main portion of the present building was completed and served as a residence hall for all the students.

"[4] John Phillips (musician), who attended Linton Hall Military School from 1942 to 1946, and later gained fame as singer, songwriter and guitarist for The Mamas & the Papas, recalls in his autobiography that he "hated the place," even though he earned good grades, made many friends, and played sports.

"[5] Students followed a strict schedule, particularly on weekdays, from rising at 6:45 a.m. to their 9:00 p.m. bedtime, with only 45 minutes of free play allocated on Mondays and Wednesdays, and two hours on Tuesdays, Thursdays, and Fridays, plus some time in the evening during 'rest' period in the dormitories.

[6] Cadets were not permitted to keep items such as food, money, or comic books, nor make or receive telephone calls, except in case of emergency.

In the 1975–1976 school year, a five-day resident program was offered to make the boarding facility available to more students.

[9] During the early 1980s, as enrollment continued to decline, the Benedictine Sisters were rethinking the role of Linton Hall as a military school.

A series of meetings and studies among the Benedictine Sisters resulted in a decision to discontinue the military program.
