Plechelm was an Irish^{[citation needed]} Benedictine monk who traveled to Rome with two fellow monks, Saints Wiro and Otger.^[1] He became a missionary first in Northumbria, England, and then in the Kingdom of Frisia, now the Netherlands. He died in Sint Odiliënberg.

Plechem was canonized by Pope Agapetus II about 950. As a result, the Basilica of St. Plechelm in Oldenzaal was built to enshrine his remains in 954.^{[citation needed]}
