History lovers got a chance to learn a little bit more about the history of the borough's most iconic park.

A free walking tour of the World's Fair sites in Flushing Meadows Corona Park took place on Sunday.

Tour guides led groups to a handful of the more than 40 World's Fair structures and sites still present throughout the park.

Stops on the tour include the Rocket Thrower, engraved granite panels and the Unisphere.

"It is a piece of New York City history that you will not find anywhere else in the world. Many people who grew up here, attended the fair or their parents and grandparents did and it is a very personal experience," said Vickie Karp, the director of community engagement at Flushing Meadows Corona Park.

The World History Walking Tours are offered every second Sunday of each month.

Participants can meet tour guides in front of the Unisphere at either 11 a.m. or 1 p.m.
