THE BRONX - The Bronx is celebrating its centennial this year.

The Bronx officially became a borough on Jan. 1, 1914, though some houses still standing in the Bronx date back to the 18th century. George Washington slept at the Van Cortlandt House, which was built in 1748, and American Revolution battles happened at the Valentine Varian House, which is now the Museum of Bronx History.

Another historical location in the Bronx is the Allan Poe Cottage on the Grand Concourse, where Edgar Allan Poe lived from 1846 to 1849.

As part of a celebration on Thursday evening, the Empire State Building will be lit up in orange, blue and white - the colors of Bronx's flag.
