Holy Trinity Cathedral was designed by renowned architect, Louis H. Sullivan. It’s an official City of Chicago Landmark and is listed on the National Register of Historic Places. The Cathedral is usually open for visits and tours on Saturday afternoons from 11am to 4pm. However, it is strongly advised that you call ahead to confirm.

The structure is rectangular, oriented along an east-west axis.  The nave is square with an inscribed octagon supporting the dome.  The dome itself is carried on eight round arches and four squinches (a section of vaulting or corbeling, set diagonally across the interior angle between two walls to provide a transition from a square to a polygonal or more nearly circular base on which to construct a dome).  From the outside, the building appears rather small. However, upon entering, the true beauty of this Cathedral is revealed and it seems much larger to the visitor.

The church is decorated with beautiful frescoes and iconography (a few dating back to the early 1900s) depicting the lives of Christ, the Theotokos (or mother of God) forefathers, fathers, patriarchs, prophets, angels, apostles, preachers, martyrs, confessors, and ascetics.

Church accounts cite a 1906 payment to one Louis Millet for repairing one of the stained glass windows.  Motifs found in the stained glass crown of the chandelier are repeated in the stencil work, which appears to confirm the attribution of all the church’s stained glass, including the chandelier, to Millet’s work.

An ornate white and gold icon screen, imported from Russia and donated in 1912 by prominent Chicagoans Charles R. Crane and Harold McCormick, separates the congregation from the sanctuary. The theme of grapes and vines on the royal doors goes back to Jesus saying, “I am the vine.”

Together with the amber-colored windows, the interior as a whole is a picture of harmony and truly must be seen to be appreciated.
