The community was established in 1885 by Archbishop
William Hickley Gross to serve the mostly Irish Catholic lumber and dockworkers in the area, located in the industrial areas of
Slabtown and what is now called the
Pearl District. A church and school, dedicated to the
Sacred Heart, were opened as a mission of
the cathedral. The cornerstone for the new church was laid on
Saint Patrick's Day 1889; still unfinished, it was dedicated two years later. St. Patrick's built a
Catholic school in 1918, operated by the
Sisters of Mercy and after 1925, by the
School Sisters of St. Francis. In addition to the Irish community, the parish registry swelled with new immigrants from
Croatia,
Slovakia, and
Slovenia. As the neighborhood became more industrialized, it depopulated, and attendance fell. The school closed in 1957. The construction of the
Fremont Bridge and
Interstate 405 further disrupted the neighborhood, and by 1972, the parish, with only 60 registered families, had reverted to a mission church under the supervision of St. Birgitta in
Linnton. In 1980, Bishop
Paul E. Waldschmidt selected the church to serve the Hispanic population of Portland. In June 1985, St. Patrick's also became home to the Latin choir
Cantores in Ecclesia. These set the stage for the revival of the parish, which celebrated its centennial in 1989. ==In popular culture==
