The cathedral crypt is the burial place of the
archbishops and bishops of Milwaukee. Constructed in 1984, the crypt
accommodates twenty-four burial vaults.
Nine archbishops have served the Archdiocese of
Milwaukee. Three of them now rest here: John Martin Henni, the first
archbishop of Milwaukee; Moses E. Kiley, who was most responsible
for the reconstruction of the cathedral after the fire of 1935; and
William E. Cousins, one of the fathers of the Vatican II Council.
Auxiliary Bishop Leo Brust, who died in 1995, is the most recent
bishop to be buried in the crypt.
