Template:PolicyCards (Civ6)
Skyscrapers is an Economic Policy Card in Civilization VI.
Strategy
Skyscrapers is the last of the wonder-accelerating policies, providing 
Production bonuses for all those from the Industrial Era and beyond. This includes Oxford University and the Amundsen-Scott Research Station (which are invaluable to players pursuing a Science Victory), as well as Cristo Redentor, the Eiffel Tower, and Estádio do Maracanã (which will do a lot to help players achieve a Cultural Victory) and the Ruhr Valley (which will benefit just about everyone).
Civilopedia entry
Until the Industrial Revolution, any structure over six stories was rare indeed and likely considered a “wonder.” Known as the “grandfather of skyscrapers,” built in 1797 AD, The Flaxmill in Shrewsbury used cast-iron columns and beams to support a five-story brick construction. Sixty years later Elisha Otis invented the “safety” elevator, and architects started to think bigger. In 1885 the ten-story Home Insurance Building in Chicago was christened, incorporating a steel framework, fireproofing, elevators, and electrical wiring … all considered indispensable in modern skyscrapers. Though they don’t really scrape the sky, some of them get pretty tall, like the Burj Khalifa in Dubai at 2,722 feet (829.8 meters).
