Henni Hall was dedicated on January 29, 1856 after a new location was chosen for the seminary along the south shore of Lake Township. The building was 4.5 stories tall, Italianate-styled, with a U-shaped floor plan. The gingerbread ornamentation was added at a later date. It was expanded in 1868 and again in 1875, and later renovated in 1989. Christ King Chapel within Henni Hall was consecrated in June 1861 by Archbishop Henni. Archbishop Michael Heiss and Fr. Joseph Salzmann, the first two rectors, are buried beneath the chapel. The seminary's Salzmann Library was erected in 1908 and now contains more than 89,000 volumes. The Miller Gymnasium, a gift from the estate of Ernest G. Miller, was dedicated in 1927.
