The parish rapidly outgrew this structure, however, and on November 13, 1870, the cornerstone for the present Gothic Revival church was laid, with construction commencing the following year.

St. Patrick's was becoming overcrowded and to better suit its members, Immaculate Conception Church was founded in the Shaw neighborhood.

Back to the beginning of the eighteenth century, most parishioners of the church were either Catholics who were original residents in this area or other immigrating Irish, and worshiping weekly was a part of their tradition.

The land of Immaculate Conception Church originally belonged to William Jones, and it was deeded by him on October 6, 1864 for $16,000, with $8,000 paid up front.

On July 2, the feast of the Visitation of the Blessed Virgin, the Most Reverend Martin J. Spalding, Archbishop of Baltimore, dedicated the new church assisted by Father Walter and Rev P. F. McCarthy of St. Patrick's.
