The Wonderland Hotel lease expired in 1992. On November 15, 1992 the Wonderland Hotel saw its last day of operation. In 1995 the Hotel was partially lost to a fire. In 2005, the remnants of the Hotel collapsed, and the National Park Service awarded a $65,419 contract to Moran Construction of Abingdon, Virginia to begin carefully dismantling the remains of the collapsed hotel. The historically significant doors, windows, bathtubs and other artifacts were set aside for permanent preservation in November 2006. These items were placed in park’s archival storage area located at the Department of Energy’s Office of Scientific and Technical Information Storage facility in Oak Ridge. Keys to the doors of its 26 rooms and a collection of ledger pages and records for the Wonderland Hotel had been previously archived by the National Park Service. In May 2016 the annex suffered a devastating fire, which is still under investigation.
