David is associated with Munktorp, a village situated in Köping Municipality, in Västmanland County. He reportedly originated Munktorp Church (Munktorps kyrka). The original church structures are known as David's Church (Davidskyrkan). There is an ancient carving of St. David. Munktorp Church is in Västerås diocese, northeast of Köping, Sweden.[5]
David became known as the Västmanland apostle (Västmanlands apostel).
An oral tradition about David of Munktorp, as retold by Grau in 1754 states that St David was so holy that he could hang his gloves on the sun rays.[6] David died peacefully in 1082 of old age. After his death, his remains were buried in Munktorps kyrka.
According to the Västerås breviary, David came to evangelize in Sweden in order to become a martyr. It further says that David "wandered among villages and towns, preaching the word of God and baptizing the converted, kept nightly prayer vigils, committing to God with tears and sighs his plentiful offspring, which he had thus born in the Lord".[7]
