Tháp Bitexco Financial Tower

"An emblem of the new Vietnam , this 68-story skyscraper, named for a Vietnamese conglomerate and designed by Venezuelan architect Carlos Zapata, is easily identified in Ho Chi Minh City’s skyline—a helipad juts out from near the top, looking a little like a flying saucer crashed into the building. Upon completion in 2010, it was the tallest building in Vietnam; it can no longer claim that title (which now belongs to the Keangnam Hanoi Landmark Tower), but its construction remains an impressive achievement. The 49th-floor wraparound Saigon Skydeck offers expansive views of the river and the city’s concrete sprawl; you'll find the same fine views at the somewhat pricey café-restaurant-bar Eon, located on floors 50, 51, and 52."
