Glamorgan Castle, unlike many other large homes, was not built to any one style. While it resembles a castle on the outside, it certainly does not on the inside.
The decorator was Louis Rorimer of Cleveland. the woodwork was furnished by Mathews Brothers of Milwaukee. The interior arrangement and decorative features employ the combination of Italian Renaissance, French Empire, Louis XV, Elizabethan and Japanese styles, each typical and distinct, each a fractional unit in expressing the triple motif--utility, order and harmony.
In the basement are the heating plant, water heaters, pumps, filters, air compressors, electric motors, transformers, elevator (no longer functional) and accessory equipment. Also conveniently housed in the basement were the bowling alleys, billiard room and large tile-finished swimming pool. A work room, storage area and Rathskeller were also in the basement.
The rotunda and floor above feature the fine lines and rich embellishments of Classic Greek architecture. Column, entablature, soffit and frieze were developed in beautiful Circassian walnut and ornamental plastering. From the rotunda, four corridors branch to the main entrance, grand staircase, north entrance and dining room. Midway between corridors are a fireplace and entrances to the reception and drawing rooms. The richly wrought bronze balustrades enclosing the stairs and circular balcony above were done by the Jackson Bronze company of New York, as were the decorative and bronze and glass doors at the main entrance. The company also furnished all the original andirons.
In the large drawing room, the empire style is carried out in all the richness of mahogany trim, ornamental plastering and decorations of green silk tapestry and gold leaf, with a massive fireplace as the principal architectural feature.
The main dining room, finished in solid oak, is a masterpiece of woodcarver's art. Done in Old English, there is an expression of grandeur in the artistry of carved wood, molded plasters, electrical lighting and mirror effect and suggesting the banquet hall of old baronial castle.
The fine tracery in the ensemble of Renaissance Art features the ladies' reception room, ornate in richly embellished plaster work, art panels, silk tapestry and expressing the concept of artistic inspiration in the elegance of proportion and harmony of color and detail.
Approached from the main stair corridors was the Japanese breakfast room with teakwood floor, bamboo trim, rattan lattice and grass cloth tapestry. Large window areas add as they carry out the Japanese mode of interior decoration.
Leading from the rotunda balcony on the second floor are the halls and passageways to rooms and enclosures, combining the modern innovations with the classic mode. Approached from the south corridor is the library, octagonal in plan and directly over the dining room on the first floor. Eight cases are built into the overhead framing, elaborate and pleasing in detail and construction. Art windows, bearing the names of English and American authors, are in harmony with the rich, dark shade of time-mellowed chestnut. In this room, devoted to study, thought and meditation, the expression is symbolic, complementary and rational.
Directly across the balcony, a north corridor (no longer in existence) led to the private guest rooms and the son's private sleeping room and bath. The entire east wing of the second floor, directly opposite the grand staircase, were the private rooms of Col. and Mrs. Morgan. This section included dressing rooms and private baths. The west wing included a playroom, a nanny's room and a large sewing room.
The plan, arrangement and decorative treatment of the top or third floor expresses the mode of simplicity. A Moorish style is seen in the smoking and card room, alcove and entry, which contrast with the plain walls and ceiling of the ballroom. The main tower room is an adjunct and conveniently a part of the ballroom.
From the tower room and turret, a winding stair furnishes easy access to the observation third floor roof. With the eye level of nearly 60 feet above grade, a magnificent view spreads like a panorama of grounds, landscape, designs and over one-half of the city.
