BROOKLYN - A new and unique map of Brooklyn will tell you just how old your favorite buildings are.

Thomas Rhiel, of "BKLYNR," designed the interactive map, which color codes more than 300,000 structures by age using recent data from the city.

Red is used to indicate new buildings, many of which are in Downtown Brooklyn, while blue shows aging buildings, including many landmarks in Brooklyn Heights.

Rhiel says the bird's-eye view gives a fresh perspective on the borough's neighborhoods and history.
