The Trinity Test Site is a must-visit point of interest for history buffs and those interested in the development of atomic weapons. Located in Alamogordo, New Mexico, this site is where the first atomic bomb was detonated on July 16, 1945.

Visitors can take a guided tour of the site, which is open twice a year on the first Saturdays of April and October. The tour includes a visit to the McDonald Ranch House, where the bomb was assembled, and to the actual site of the explosion, which is marked by a stone obelisk. The tour also covers the history of the Manhattan Project and the science behind the atomic bomb.

One of the unique things visitors can see at the Trinity Test Site is the "green glass" formed by the intense heat of the explosion. This glass is a rare occurrence and can only be found at atomic bomb sites. Visitors can also see original buildings and equipment used in the Manhattan Project.

Overall, the Trinity Test Site is a fascinating and important piece of American history. It offers a unique opportunity to learn about the development of atomic weapons and their impact on the world.
