I served my mission 1977-78 in Buenos Aires, Argentina. When I was on my mission, the closest temple was in Sao Paolo, Brazil. We prayed hard for a temple in Argentina. At missionary reunions after my mission we donated towards the temple. And then it happened, about five years after my mission.
It was announced that a temple was going to be built close to Ezeiza International Airport. Hermana Rosaura Corsi sent me the program of the ground breaking and dedication of the property. Bruce R. McConkie presided, spoke and offered the prayer. This was in 1983.It was dedicated in in 1986 by Thomas S. Monson. It was recently remodeled and expanded and rededicated in September of this year by Henry B. Eyring.
