Located at 700 West Adams Street, it has been described as the "cornerstone of Irish culture" in Chicago.

In the 1850s, the present church building was constructed of yellow Cream City brick from Milwaukee.

By the 1880s, most of the parish was composed of Irish-Americans, and from 1912 through 1922, the interior was redecorated by Thomas A. O'Shaughnessy and others in the Celtic Revival style.

Today, Old St. Pat's is known for hosting an annual summer block party, which it describes as the "world's largest".
