Americas
The largest mountain ranges are the Andes and Rocky Mountains. The Sierra Nevada and the Cascade Range reach similar altitudes as the Rocky Mountains, but are significantly smaller. In North America, the greatest number of fourteeners are in the United States, and more specifically in the U.S. state of Colorado. The highest peaks of the Americas are located in the Andes, with Aconcagua of Argentina being the highest; in North America Denali (Mount McKinley) in the U.S. state of Alaska is the tallest.
Buenos Aires
In 1919, the construction of Palacio Barolo began. This was South America's tallest building at the time, and was the first Argentine skyscraper built with concrete (1919–1923). The building was equipped with 9 elevators, plus a 20-metre high lobby hall with paintings in the ceiling and Latin phrases embossed in golden bronze letters. A 300,000-candela beacon was installed at the top (110 m), making the building visible even from Uruguay. In 2009, the Barolo Palace went under an exhausive restoration, and the beacon was made operational again.
