The Ritz-Carlton, St. Louis: Clayton business district Georgian palace with Casa Don Alfonso by Alfonso Iaccarino, indoor pool, and The Cigar Club
Reigning with grand Georgian colonial and aristocratic Midwestern palace architectural nobility in the prestigious business and residential enclave of Clayton in St. Louis, Missouri, United States (just steps from Forest Park, Washington University, and the St. Louis Art Museum, 15 minutes from St. Louis Lambert International Airport and the Gateway Arch), The Ritz-Carlton, St. Louis opened in 1990 as Missouri’s premier luxury grand palace. The 299-room luxury haven combines polished cherrywood boiserie, roaring marble fireplaces, and a 3-million-dollar private collection of 18th- and 19th-century oil paintings and crystal chandeliers. Featuring the acclaimed southern Italian dining institution Casa Don Alfonso by Michelin-starred culinary legend Alfonso Iaccarino, the exclusive members-only Cigar Club, a heated indoor freshwater swimming pool with Roman columns, and a 24-hour state-of-the-art fitness center with saunas and steam rooms, this property is St. Louis’s ultimate luxury grand palace.
Arrival introduces travelers to unvarnished Midwestern aristocratic glamour and Clayton neighbourhood splendour: liveried doormen greet guests beneath the classical Georgian portico on Forsyth Boulevard before entering the warm mahogany lobby with crackling marble fireplaces, crystal chandeliers, and chilled local Missouri cider or bourbon with warm artisanal canapés. Day-one logistics focus on coordinating bespoke St. Louis cultural, park, and culinary pursuits: taking private guided walks through the 1,300-acre canopy of Forest Park and the St. Louis Art Museum (5 minutes away), private guided tours of the iconic Gateway Arch on the Mississippi riverfront (15 minutes away), private luxury shopping in Clayton’s boutique district and the Saint Louis Galleria (steps away), swimming in the indoor heated pool, indulging in soothing in-room massage therapies, sipping rare vintage bourbons in The Lounge, and reserving dinner at Casa Don Alfonso.
Palace living balances active St. Louis cultural discovery with serene Midwestern retreat wellness: The In-Room Wellness Retreat and Clayton Fitness Center feature private luxury massage therapies, Finnish saunas, steam rooms, the indoor heated pool, and therapies utilizing organic botanicals and ESPA skincare. Dining is an extraordinary Italian-American culinary summit: southern Italian gastronomy at Casa Don Alfonso (featuring Campania pasta, Neapolitan pizzas, and Italian Grand Crus), live music and craft cocktails in The Lounge, and 24-hour in-room royal dining.
Accommodations comprise 299 rooms and luxury executive suites styled in warm amber and navy tones, tailored cherrywood millwork, private furnished balconies, and picture windows framing the Clayton skyline or Forest Park ranging from 42 to 185 square metres. Each residence features plush king beds with custom linens, and marble bathrooms with deep soaking bathtubs, embedded TV mirrors, and custom Diptyque Philosykos amenities.
