The Flatiron Building in New York City was built in 1902 by the same architect who designed Union Station in Washington D.C. It is considered one of the first skyscrapers and still stands over 100 years later in the Flatiron District. Some of its original tenants included a building company known for constructing skyscrapers and an insurance company founded in the U.K. in 1762. Taking a tour with OnBoard Sightseeing Tours allows visitors to learn about the building's history and past tenants.
