McDonald Ranch House The McDonald Ranch House, also known as Trinity Site, in the Oscura Mountains of Socorro County, New Mexico, was the location of assembly of the world's first nuclear weapon.

The completed bomb was winched up the test tower the following day and detonated on July 16, 1945 as the Trinity nuclear test.
