The Lake Hotel is one of a series of hotels built to accommodate visitors to Yellowstone National Park in the late 19th and early 20th century. Built originally in 1891, it was re-designed and substantially expanded by Robert Reamer, architect of the Old Faithful Inn in 1903. In contrast to the Old Faithful Inn, the Lake Hotel is a relatively plain clapboarded Colonial Revival structure with two large Ionic porticoes facing Yellowstone Lake.
