The Ukrainian Catholic Cathedral of St. George was designed by architect the Very Reverend Philip Ruh, O.M.I.

[2] The organizational meeting of the Ukrainian Catholic Parish of St. George took place on September 29, 1912 at which the first Executive was elected.

The church is a massive mason structure which stands on a high concrete basement measures 104 x 90 feet (27 m); the intersecting arms are 30 feet (9.1 m) wide.

The central area of the church is dominated by a large octagonal dome which is reinforced by the arcades of the vaulted ceilings and is supported by four massive octagonal columns.

In 1950 to 1955 the icons and artistic decoration of the church were done by Theodore Baran, member of St. George's parish.
