Research Narrative
Landmark Context
St. Gelasius Church Building is fixed in the city's landmark record at 6401-09 S Woodlawn Av. City records connect the site to a construction date of 1923-28 and credits Henry J. Schlacks. It was designated on January 14, 2004. St. Gelasius Church Building already ties religious architecture, congregational history, and immigration and neighborhood change to one real building before archival digging begins.
St. Gelasius Church Building becomes easier to read on site when attention turns to entry hierarchy, towers, and symbolic facade work, parish or congregational buildings nearby, and later reuse, subdivision, or adaptive change. The point is not just to admire the building but to understand how worship, community identity, and later reuse remain visible in the building.
Research Starting Points
St. Gelasius Church Building starts to deepen once research reaches congregational records, permit files, and historic photographs and neighborhood reporting. That is where early landmark facts begin to connect to a fuller chronology of change, use, and interpretation.
St. Gelasius Church Building still needs permits, photographs, and comparison, but the landmark record gives that work a stable point of return.
