 For this purpose , Ross Edwards bought Fundo Pichilemu , a farm , from Juan Esteban Torrealba Maturana in 1885 . There was a little hotel in Fundo Pichilemu called La Posada , which he converted into a first @-@ class hotel called the Gran Hotel Pichilemu ( now the Agustín Ross Hotel ) . Following the development of the Gran Hotel Pichilemu , Ross Edwards saw the need of creating " a seaside resort with all the comforts and luxuries capable of seducing the Chilean aristocracy ; " for this purpose , he conceived the idea of creating a park , and a post @-@ office building . Afterwards , Agustín Ross installed amenities such as a laundry , stables , and stairways , among others , according to local historian José Arraño Acevedo , turning Pichilemu into a summer resort town for affluent people from Santiago and Mendoza , Argentina .
