The Adirondack History Museum, established in 1955, is in a former school in Elizabethtown, an Adirondack gateway town on the east side of the park. It has eight permanent exhibits and a space for rotating exhibits. Inside, an interactive relief map focuses on Essex County (where the museum is located), which spans from the Lake Champlain shoreline to the High Peaks of the Adirondacks. One room in the museum is dedicated to an exhibit about hiking the High Peaks. Another room is about the work of Arto Monaco, the early theme park designer who was from Elizabethtown, and who built the Land of Makebelieve in Upper Jay.
