The focal point of the station was the Grand Hall, which featured a 65-foot barrel vaulted ceiling with stained glass windows. Today this magnificent historical site has been transformed into a [luxury hotel property](https://www.trendhunter.com/trends/fairmont-golden-prague) that remains a must-see destination for tourists. The Grand Hall was recently updated as part of a renovation project with the largest permanently installed indoor projection mapping show in the United States. The amazing experience immerses visitors in a feature presentation across the entirety of the vaulted ceiling. The various shows and vignettes focus on key points throughout the city's history and are bolstered by surround sound tracks customized to each of the vignettes. ## Trend Insights (Trend Hunter) - Score: 2.4/10 - Popularity: 12% | Activity: 51% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, South America, Europe, Asia, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Multimedia](https://www.trendhunter.com/multimedia) ## Key Themes ### Key Themes Behind This Trend - **Projection Mapping in Historical Sites:** The use of projection mapping technology to showcase historical events and landmarks. - **Permanent Indoor Projection Mapping Installations:** The installation of permanent indoor projection mapping displays in commercial properties and tourist destinations. - **Multi-sensory Experience:** The incorporation of customized surround sound tracks to enhance projection mapping experiences. ### Where This Applies - **Hospitality:** The use of projection mapping technology to enhance the guest experience in hotels and resorts. - **Tourism:** The use of projection mapping technology to create immersive experiences for tourists visiting historical sites and landmarks. - **Events:** The use of permanent indoor projection mapping installations in event venues to offer unique and interactive experiences for attendees. ## Related on Trend Hunter - [Rebuilt Historic Train Stations](https://www.trendhunter.com/trends/train-station-in-the-forest.md) - [LED-Wrapped Airport Renovations](https://www.trendhunter.com/trends/pragues-airport.md) - [Artfully Designed Train Stations](https://www.trendhunter.com/trends/design-studio-mad.md) - [Next-Gen Whiskey Bars](https://www.trendhunter.com/trends/bulleit-limitless-lounge.md) - [Digital City-Inspired Art Works](https://www.trendhunter.com/trends/grand-central-station.md) - [Immersive Digital Art Galleries](https://www.trendhunter.com/trends/the-reel-store.md) - [Accessible 3D Station Maps](https://www.trendhunter.com/trends/3d-station-maps.md) - [Performance Hall Expansions](https://www.trendhunter.com/trends/powell-hall.md) - [Latticed-Steel Transport Hub Columns](https://www.trendhunter.com/trends/metropolitan-station.md)
