Located in the park near Lake Palermo in Buenos Aires. The planetarium was built in 1966 and has a huge 20 meter dome with a distinctive shape and wonderful light up in the night. The renovated planetarium reopened its doors in 2012. The new system is a hybrid system combining realistic and rich sky of Megastar-IIA with versatile features of Digital Sky by Sky-Skan (USA). This project became the first Ohira Tech’s installation in South America.
