The station served 22 railroads at its peak and expanded in 1904 to welcome millions of visitors to the St. Louis World's Fair.

Today the property operates as a full-service hotel and event destination in downtown St. Louis.

Mount Hope Hilltop Venue is a historic barn wedding destination set on a scenic hilltop in Michael, Illinois. The property traces its roots to the Mount Hope Settlement, established before 1840 in Calhoun County. The centerpiece three-story barn was constructed around 1830 and rebuilt and expanded between 1860 and 1870, with its basement hand-excavated by removing 750 tons of dirt and original redwood timbers shipped in by steamboat from Hamburg. At its peak around 1900, the settlement included tenant houses, blacksmith shops, a sawmill, and more than 15,000 orchard trees. Today, the property combines that timeless architecture with a koi pond, apple orchard, and sweeping hilltop views. Event spaces include a rustic reception hall with soaring pitched ceilings and glowing chandeliers, a historic three-story ceremony barn with exposed beams and warm wood walls, multiple outdoor ceremony areas, and The Cellar Room — a screened-in space beneath the Red Barn featuring stone walls and a raw-edge wooden bar overlooking the pond.
