It is located in the Andes mountain range, in the Mendoza Province, Argentina, and lies northwest of its capital, the city of Mendoza, about from San Juan Province and from the international border with Chile.

Alas Building
Alas was the tallest building in Buenos Aires between 1955 and 1995, when it was surpassed by the Le Parc tower. It has long been a vital part of the skyline of Buenos Aires, together with other, neighboring buildings on Leandro Alem Avenue, such as the similar Comega Building (1930), as well as those built in the International style during the 1970s (notably the Catalinas Norte development). Recently, however, it was overshadowed by the construction of several towers in the Puerto Madero area; as of 2009, it remains the 20th tallest building in Argentina.
