About the St. Louis Union Station Hotel

This unique, national historic landmark connects with the past while you enjoy the luxury of the present. The nightly award-winning 3D light show in the Grand Hall lobby at the St. Louis Union Station Hotel is amazing! The Grand Hall, built in 1894, draws you in with its uniquely designed architectural archway, fresco and gold-leaf detailing, mosaics and art glass windows. The Grand Hall is a St. Louis historical landmark and unique place to enjoy a drink. ASPET posters will be displayed in the Midway area, which was the hub for travelers in the early 1900s as they waited for arriving passengers and departing trains.

The hotel’s guest rooms are fully renovated, beautifully modern and rich in history. Many of the rooms give a nod to Union Station’s past with artwork and decor depicting railroad themes. The hotel is rated 4-Diamonds by AAA.  In addition to housing the hotel, the Union Station complex includes multiple restaurants and family friendly attractions such as an aquarium, Ferris wheel, carousel, mirror maze, ropes course, mini golf, and a complimentary showcase of pyrotechnics and dancing light at the Fire & Light Show held daily on the lake.
