Book Cadillac Hotel
The Book Cadillac Hotel, now operating as the Westin Book Cadillac Detroit, is a historic luxury hotel located on Washington Boulevard in downtown Detroit, Michigan. Originally opened in 1924, the hotel replaced an earlier structure on the same site and quickly became one of the city's most recognizable landmarks. Designed by architect Louis Kamper in the Italian Renaissance style, the 33-story building was among the tallest hotels in the world at the time of its completion. After decades of decline and a prolonged period of abandonment, the building was restored through a major renovation and reopened under the Westin brand, becoming a symbol of downtown Detroit's broader revival.[1]
History
The Cadillac Hotel
The story of the Book Cadillac Hotel begins with the earlier Cadillac Hotel, which occupied the same site on Washington Boulevard. In 1885, businessman Daniel Scotten constructed a four-story commercial block on the property, initially leasing it to a grocery operation. When that business failed, Scotten converted the building into the Cadillac Hotel in 1888.[2] He then acquired and demolished the adjacent Antisdel House to expand the hotel's footprint. By 1891, the Cadillac Hotel had grown to fill the entire block between Washington and Shelby Streets along Michigan Avenue.
The Cadillac Hotel established itself quickly as one of Detroit's premier lodgings. It hosted five U.S. Presidents during its operation: Benjamin Harrison, Grover Cleveland, William McKinley, Theodore Roosevelt, and William Howard Taft.[3] That era didn't last. By the early 20th century, the hotel struggled to compete with newer establishments including the Statler Hotel and the Pontchartrain Hotel, both of which offered more modern accommodations and amenities.
Construction of the Book-Cadillac
In 1917, the Book brothers, Herbert, Frank, and J. Burgess Book Jr., purchased the Cadillac Hotel. The site held personal significance: all three brothers had been born within the walls of the original building. Six years later, in 1923, they made the decision to demolish it and build something larger in its place. The Book brothers had already been reshaping Washington Boulevard through a series of development projects, including the Washington Boulevard Building and the Book Building, with the intention of making it Detroit's most prominent commercial destination.[4]
Construction of the new hotel was entrusted to architect Louis Kamper, who had collaborated with the Book family on earlier projects along the boulevard. Kamper designed the building in the Italian Renaissance style, incorporating Venetian decorative elements throughout the interior and distinctive ziggurat-shaped corner features that gave the upper floors a stepped, sculptural silhouette. Groundbreaking took place in 1923. The 33-story Book-Cadillac Hotel officially opened on December 8, 1924, and at the time of its completion it ranked among the tallest hotels in the world.[5]
Decline and Abandonment
The hotel operated as a premier destination through much of the mid-20th century. But Detroit's broader economic decline, accelerated by deindustrialization and population loss in the latter half of the century, hit Washington Boulevard hard. The Book-Cadillac Hotel eventually closed, and the building sat vacant for years, deteriorating alongside much of the surrounding downtown. The abandonment of such a prominent structure came to represent the larger challenges facing the city during that period.
Renovation and Reopening
A major rehabilitation project eventually brought the building back. The restoration effort, which required significant investment and coordination with historic preservation guidelines, converted the upper floors into residential condominiums while returning the lower floors to hotel use. The hotel reopened as the Westin Book Cadillac Detroit, with Westin, part of the Marriott International portfolio, operating the lodging portion of the property. The renovation was widely cited as one of the more ambitious adaptive reuse projects in Detroit's recent history, helping to anchor renewed interest and investment in the Washington Boulevard corridor.
Architecture
Louis Kamper's design for the Book-Cadillac drew heavily from Italian Renaissance precedents. The building's exterior featured elaborate stonework and classically derived ornamentation, while its stepped corner towers, inspired by Mesopotamian ziggurat forms, gave the skyline profile an unusual and distinctive character.[6] Kamper applied a similar sensibility to the interior, where the Italian Garden and the Venetian Ballroom became the hotel's most celebrated social spaces. Both rooms featured ornate plasterwork, decorative tile, and period furnishings intended to evoke the atmosphere of European grand hotels.
At opening, the hotel contained over 1,200 guest rooms, each with a private bathroom, which was a notable feature for its time. The building also included multiple ballrooms, dining rooms, lounges, and retail spaces, making it a self-contained destination rather than simply a place to sleep. The scale and ambition of the project reflected the economic confidence of Detroit in the early 1920s, when the automobile industry was driving unprecedented prosperity across the region.
Geography
The Book Cadillac Hotel occupies a prominent position at the corner of Washington Boulevard and Michigan Avenue in Detroit's central business district.[7] The location was not accidental. The Book brothers selected the site as part of a deliberate effort to anchor Washington Boulevard as Detroit's premier commercial and hospitality corridor, positioning their hotel to draw guests from the theaters, restaurants, and businesses they envisioned lining the street. The nearby Statler Hotel had already established the boulevard as a viable lodging destination, and the Book-Cadillac was intended to compete directly with it.
The surrounding area has changed considerably since 1924. Washington Boulevard saw significant decline during the second half of the 20th century, but ongoing investment in downtown Detroit has brought renewed activity to the neighborhood. The hotel sits within walking distance of several dining and entertainment options. Nearby restaurants include Le Supreme and La Lanterna, both accessible on foot from the hotel entrance. Sakazuki, a cocktails and appetizers establishment, operates in close proximity to the building as well. The walkability of the immediate area is frequently noted by guests, given the hotel's position within the denser fabric of downtown.
Cultural Significance
The Book-Cadillac Hotel functioned as more than a hotel from its earliest years. Its ballrooms and banquet spaces became central venues for Detroit's social calendar, hosting galas, political dinners, and civic events throughout the 1920s and 1930s. The Venetian Ballroom in particular drew large gatherings, and the hotel's restaurants attracted a regular clientele from the city's business and professional communities.
The building's history tracks closely with Detroit's own trajectory: ambitious and prosperous in its early decades, strained and eventually shuttered as the city's fortunes shifted, and later the subject of a restoration effort that reflected cautious optimism about downtown's future. It's one of the more complete examples of that arc within a single structure. The renovation and reopening under the Westin brand returned the hotel to active use and helped signal to developers and investors that historic buildings in Detroit's core could be viably rehabilitated.
Notable Residents and Guests
The Book brothers themselves held a unique connection to the property. Herbert, Frank, and J. Burgess Book Jr. were all born inside the original Cadillac Hotel, which stood on the same site before they purchased and demolished it.[8] That personal history shaped their investment in the replacement building, which they designed explicitly as a landmark rather than simply a commercial property.
The original Cadillac Hotel hosted five U.S. Presidents: Benjamin Harrison, Grover Cleveland, William McKinley, Theodore Roosevelt, and William Howard Taft. The Book-Cadillac, once opened, continued to attract prominent figures from business, politics, and entertainment, drawn by the hotel's central location and its reputation as the finest accommodation available in Detroit at the time. Specific guest records from the hotel's mid-century operation aren't comprehensively preserved in public archives, but the hotel's standing as a top-tier property throughout its active years ensured a steady flow of notable visitors.
