 In the early 20th century , the parish decided that the old church should be remodelled into a school and a convent for the teachers , and that a new church should be built . Brother Leonard <unk> , a Franciscan architect , drew up plans for a church ; but financial constraints precluded its construction . Instead , a temporary basement church was built just west of the old church building . It is not known whether the design of the basement used <unk> 's plans . Construction of the basement church began in July 1902 , services were held there beginning in September 1902 , and it was dedicated in February 1903 .
