the mansions which are characteristic of the city were built during this period as well. Throughout the first half of the 20th century, Capilla del Monte saw its growth in size and popularity as a consequence of the arrival of new inhabitants. New businesses opened and the population further increased. The Los Alazanes Dam was built in the 1940s because a broader supply was needed to provide the new inhabitants with water. The 1970s saw a recession in tourism, mostly because of the National Reorganization Process of 1976-1983, a dictatorship that struck Argentina and prevented the population from moving freely across the nation. Until the 1970s, the city's population was located mostly around the train station. That building now houses the Center of Tourist Information. 1986 – present On January 9, 1986, the famous Huella del Pajarillo incident took place. That night, a dark, circular footprint of 100 meters in diameter appeared on Mount Pajarillo, resembling a UFO landing.

In 2012, the Alien Festival was created in the city, and it has been celebrated almost every February since then. The participants in this festival embrace and promote this new identity by dressing up as extra-terrestrials or fictional characters from popular science fiction sagas such as Star Wars and Star Trek.
