The ESO Guesthouse in Santiago from the air

The Guesthouse was bought in 1964 as a pied-a-terre in Santiago and served in the early years for both the administrative offices and for lodging visitors from Europe. In the early 1970s it was contemplated to sell the Guesthouse and incorporate its function for visitors into the Vitacura Headquarters building. The idea was not, however, pursued any further.
