[citation needed] Founded in 1960, Mercy High School is located on a 26-acre campus in Northeast Baltimore.

Opened at the request of the Archbishop of Baltimore who saw a need for a large, modern, centrally located Catholic high school for girls, Mercy High School was established in anticipation of the entrance of the first wave of baby boomers born in 1946.

Today, students from more than 69 ZIP codes throughout Central Maryland and Southern Pennsylvania attend Mercy.

[7] On September 14, 1964, George Harrison visited Mercy the day after the Beatles played a concert in the city.

A plaque placed above the fountain from which he drank from says Harrison’s visit was “the only known visit by a member of the group to an American high school during the height of Beatlemania.”[8] Frank Lidinsky, who commissioned the plaque, verified the information by email with Beatles historian, Mark Lewisohn.
