The Brookland area evolved in the early 1870's, when the Baltimore-Ohio Railroad opened its western branch line in this area, alongside the fine 1840 Greek Revival Mansion of Colonel Jehiel Brooks. By the late 1880's, Catholic University established its location just north of Brooks estate. These developments gave way to a new Washington neighborhood, taking its name from Colonel Brooks. Affectionately nicknamed "Little Rome", this neighborhood boasts of more than 60 Catholic Institutions, including a large, new museum - Pope John Paul II Cultural Center - as well as the city's oldest cemetery and the magnificent gardens of the National Arboretum and the Franciscan Monastery. Prominent African-American architects Hilyard Robinson and Howard H. Mackey designed 13 international-style houses here, including that of the Nobel Peace Prize winner Ralph Bunche.
