On one side was a long seminary building and on the other was an L-shaped larger, but similar architectured structure built for the secular College, after it was established in 1805.

In the 1970s, the Victorian buildings were unfortunately also razed leaving St. Mary's Park with a historic bandstand to now surround the old Chapel and Mother Seton House.

To the east in the 1980s was constructed a four-lane landscaped parkway with median strip of the Martin Luther King, Jr. Boulevard, edged by short brick retaining walls which curved around the west side of downtown Baltimore like an inner "beltway".

The bricks were originally made for architect Benjamin Henry Latrobe's Baltimore Cathedral/Basilica of the Assumption of Mary (constructed 1806-1821), but it was eventually built of stone blocks.

The bricks were then purchased for this project for $3,000.00, contributed by Charles Carroll of Carrollton, (1737-1832), last surviving signer of the Declaration of Independence and at one time the richest man in America.

The Josephite Fathers religious order has a special ministry among the African American community within the Roman Catholic Church.
