PHILADELPHIA (CBS) – There is a century-old hidden treasure for children in East Fairmount Park.

A gift to the children of Philadelphia, Smith Memorial Playground and Playhouse first opened its doors in 1899 through funding by Richard and Sarah Smith. Executive Director Meg Wise says the goal is to give children a free, safe and beautiful place to play.

“There’s a 24,000-square-foot playhouse, which is full of trains and dinosaurs and dump trucks — all sorts of play equipment for kids 5-years-old and younger. Then there’s a six-and-a-half acre playground for kids 10 and younger.”

And the playground has all sorts of unusual items for kids to enjoy.

“There’s spinners and climbers and swings and just dozens and dozens of pieces of equipment.”

One of the biggest attractions is the Ann Newman Giant Wooden Slide. “It’s only 105 years old. And everyone who comes to Smith really — that’s the highlight of the playground.”

Smith is holding its annual adults-only Party on the Playground fundraiser on May 16th at the Playhouse. For more info, go to SmithKidsPlayPlace.org.
