The Baldpate Inn The Baldpate Inn is a hotel located in Estes Park, Colorado, with a designation on the National Register of Historic Places. It was founded in 1917 by Anglo-American brothers Charles Mace (combat and commercial photographer, 1889-1973), and Gordon Mace, and their families. The Inn is known especially two reasons: the hotel was named for the popular mystery novel, play and films "Seven Keys to Baldpate" by Earl Derr Biggers, and was eventually accepted to be the "true" Baldpate by the author. While the hotel originally gave away keys as curios, today it is known for its collection of more than 20,000 keys, usual, unusual and figurative, that have been offered to the inn by visitors, hotel guests, and dignitaries from all over the world.
