Welcome to Immaculate Conception

Catholic Church


Immaculate Conception Church is a dynamic, welcoming, multicultural, Catholic community of believers, who work together honoring and serving the Lord through our gifts, talents and abilities. We are challenged by our baptismal call and nourished by the Eucharist to bring the good news of Christ to all.

Immaculate Conception inspired by the Holy Spirit, we live the Good News of Christ through Worship, Community and Stewardship. Immaculate Conception is the oldest standing Catholic Church in Seattle. Founded by the Jesuit Fathers, the Church was built in 1904 and declared a Historical Landmark by the Seattle Landmarks Preservation Board in 1974.

Today the parish, led by Priest Administrator, Father Maurice Mamba Ngalamulume, is a rich, diverse and vibrant community of worshippers from all ethnic backgrounds and histories. Immaculate Conception Church continues its long and proud history in Seattle and plays an important role in the growth of the Archdiocese.
