The seminary held its first classes in the fall of 1939. The member of the first class were ordained after graduating the following spring. The seminary continued to serve the Eastern Province of the Congregation until 1969. By that time, the number of candidates to the Vincentian Fathers had dropped to such a point that the seminary was opened to students for dioceses of the region and other religious institutes. The last class graduated in 1990, the 50th class to have done so. The seminary had trained some 500 men for the priesthood by that time.[4]
The Roman Catholic Archdiocese of Philadelphia began to make use of the facilities for its own seminarians. In 1996, the Vincentian Fathers sold the property to the Archdiocese, which converted into use as a retreat center.[4]
The buildings
Chapel
In 1954 the Chapel of Mary Queen of all Saints was opened for worship by the Vincentian community.[1]
The chapel was built in the form of a cross composed of the nave and the transept, with a semi-circular apse around the altar. The Vincentian Fathers and seminarians sat in choir stalls of white oak, with stone work of white Indianalimestone, ornamented in places with carved inscriptions. It contains a shrine to Our Lady of the Miraculous Medal. The stone work in the shrine is of Kentuckysandstone.[5]
The architectural style of the chapel is a fusion and adaptation of ancient forms. The exterior was done in the Romanesque style, and the interior uses the Romanbarrel vault for the nave. The dome of the apse, directly above the main altar, was done in a Byzantine style. The apse dome features a tile mosaic executed by Hildreth Meiere[6] in the Art Deco style depicting Our Lady surrounded by six saints who were known for a strong devotion to her. They are:
The tabernacle is not marble, as is commonly used, but made of white onyx. The crucifix has the body of Jesus in ivory-colored linden wood, which stands out from the darker tones of the zebrawood cross, with its edging and trim done in sheet copper.[5]
Tower
The complex includes a tower that dominates the front of the main building and which features the crucifixion. In its foyer, mosaics depict the life and works of St. Vincent de Paul, founder of the Vincentians, and notable members of the Congregation. Sayings of Vincent de Paul are sculpted into the stone.[5]
