Old Faithful Historic District, Historic district in Yellowstone National Park, US.

The Old Faithful Historic District covers the built-up part of the Upper Geyser Basin around the Old Faithful Inn and Old Faithful Geyser. It holds the inn by Robert Reamer, the Old Faithful Lodge by Gilbert Stanley Underwood, the Snow Lodge, three stores, two service stations, five dormitories, ten support buildings and guest cabins. The district lies on the 140-mile Grand Loop Road Historic District.

The district developed in the early 1900s as Yellowstone grew and drew more visitors to the park. The structures show how park management tried to build tourism infrastructure during this founding era.

The buildings showcase craftsmanship from the early park era, with stone and timber that reflect how builders worked with local materials. You can see these building methods in the details of the structures as you walk around.

The location offers several types of lodging and restaurants to suit different needs and budgets. It makes sense to arrive early to avoid crowds around the geyser and to explore the buildings at your own pace.

The Lower Hamilton Store, built as the Klamer Store in 1894 and sold to Charles Hamilton in 1914, hangs a sign over its salesroom entrance spelling HAMILTON STORES in burled branches and logs. Its second floor holds a small sitting room called "The Million Dollar Room," papered with canceled checks totaling $1,000,000, a fact reportedly recorded in Ripley's Believe It or Not.
