Mound Science & Energy Museum Association

Mound Laboratory and the Mound site, located at southern edge of Miamisburg, between Dayton and Cincinnati, in Southwestern Ohio, hold significant places in the history of the Nuclear Age and in the hearts and minds of the dedicated scientists and workers who labored there for more than 50 years. The people, the plant, their research and manufactured items were at the leading edge of the Nuclear Age in the United States. Mound built components went with NASA to the moon, Mars, Jupiter, Saturn, Uranus, Neptune and the sun reliably powering their instruments and keeping them at operational temperatures. They are still continuing in the same vein into interstellar space.


The Mound Science and Energy Museum Association (MSEMA) is a non profit organization that was established to collect, preserve and make publicly accessible the heritage of the Mound Laboratory, its workers and its site. To that end, MSEMA has partnered with Dayton History to provide professionally designed enhanced displays that better educate visitors to the museum about the important work done at this site that helped win the Cold War. In honor of that effort the name has been changed to the Mound Cold War Discovery Center. In addition to the enhanced displays, there is a focus on educating the visitors on important related subjects like radiation. Operating hours have been expanded and admission is still free.
Open Hours to Public
The Mound Cold War Discovery Center is open to the public Wednesday-Saturday 10:00 am to 4:00 pm.
