It was torn down in a modernization effort in 1959, by order of Archbishop Brady.
Brady lived at St. Catherine's College during that time (where his sister, Sister Mary William Brady served as the fifth president of the College of St. Catherine from 1955 to 1961), while a "modern" episcopal residence was constructed.
This modern residence, today listed for sale, proved a reckless disaster, thanks to its flat roofs, which leaked from heavy melting snow every spring.
The four poster bed the Cardinal slept in has survived and is today still in use in the Cathedral rectory.
All of my older relatives remember fondly seeing this city landmark before its untimely destruction. It brings to mind the demolition of the Victorian Gothic Ryan Hotel, another Saint Paul city landmark, destroyed in 1962 to make room for a parking lot. Or the demolition of Schuneman’s, now also an empty parking lot.
