Since it was founded by the Diocese of London in 1912, the seminary has produced more than 1,000 priests (including 23 who became bishops) and has educated permanent deacons and lay graduates.

The 25-acre riverside site on which the seminary stands was donated by Sir Philip Pocock, from a prominent London Catholic family.

In addition, the exterior stonewalls and slate roof were restored, and modern heating and cooling systems were installed.
