does anyone know why the St. Stanislaus Jesuit Seminary closed?

Answer 1

"The land given to the Jesuits became the site of St. Stanislaus Seminary. The Rock Building on Howdershell Road was part of the site and housed the Museum of Western Jesuit Missions beginning in 1970.

In 2002, the Jesuits sued the St. Stanislaus Historical Museum Society, which had operated the museum since its founding, over ownership of its contents. The society claimed the Jesuits had abandoned the museum’s collection for the past 30 years, while the Jesuits contended they still owned the building and its contents.

St. Louis County Associate Judge Gloria Clark Reno ruled in favor of the Jesuits last October."

"At one time St. Stanislaus was totally self-sufficient, like a medieval monastery. Its 999 acres included an orchard, chicken ranch, cattle barn, wheat fields, vine-yards, butcher shop, creamery and bakery. After the seminary closed in 1971, the newer building were sold to the Gateway College of Evangelism."

One can conclude that it was part of a consolidation effort, also economic because fewing men were entering the priesthood following Vatican II. Also the move to the University made that institution stronger.
