Its initial location was S. Julião da Barra Fort, in Oeiras. It moved a first time to a former hospital-convent in Luz in 1814 - during its first years it moved two more times before finally resettling in Luz in 1859.
Initially intended to shelter the sons of military officers stationed abroad to fight the French armies and turn them into army officers, it endured through the French Invasions until the present. It is one of the eldest schools of Portugal and Europe and the most decorated military institution in Portugal.
Colégio Militar has been through many regime changes, revolutions and wars, providing a military education for thousands of youngsters who join at the age of ten and finish just before entering university or military academies. It is quite distinctive in its educational method, in which the elder students are ranked and put in command of the younger, perpetuating many rich and ancient traditions that keep a tight bond in the student corps (that often last throughout their lives).
Academic program 
Teaching is led by a mixed staff of military and civilian teachers. There is a high sports component in the curriculum which includes, among others, fencing, horse riding, competition gymnastics, and shooting.
Many of its former students have influenced the development of the Portuguese society since the mid-19th century, such as five presidents of the Portuguese Republic (Field Marshals Gomes da Costa, Óscar Carmona, Craveiro Lopes, António de Spínola and Costa Gomes), prominent military men such as Morais Sarmento and Óscar Monteiro Torres, writers such as Manuel Pinheiro Chagas and Júlio Dantas, explorers like Serpa Pinto and Henrique Carvalho, artists, musicians and actors such as Tomás Alcaide, Raúl de Carvalho, Artur Semedo, Raúl Ferrão and Luís Esparteiro, politicians such as António Sérgio, Humberto Delgado and Tito Morais and many others. About 15,000 students have graduated from Colégio Militar.
Its anniversary is celebrated on March 3 with a parade descending "Avenida da Liberdade", Lisbon's main avenue. Former students can be seen shouting their war cry "Zacatraz" - these can also be recognised by the use of the informal symbol, the "Barretina", on their lapels.
The Portuguese Colégio Militar gave birth to a net of twelve military schools in Brazil (Porto Alegre, Santa Maria, Curitiba, Rio de Janeiro, Belo Horizonte, Juíz de Fora, Salvador, Recife, Fortaleza, Manaus, Brasília and Campo Grande) built in cooperation with the Portuguese experience of a centenary school with high levels of success.
