It's been a staple in the midstate, and in American history - but tomorrow, the original Hershey Museum will close its doors for good.

The sign hanging inside the Hershey Museum says it all - "Built on Chocolate." For 75 years, kids and adults from all over the country and the world came to Hershey, Pennsylvania to see where all the chocolate comes from.

"I have not been to Hersheypark since my childhood, so it was really great for us to come here," said museum-goer Tom Rock. "We really wanted to visit the museum because it's so historical."

The museum was founded in 1933 by Milton Hershey, built to showcase the history of the area and what's now called one of the world's largest chocolate empires. At the museum, you can see a cancelled check that officials say was supposed to serve as a deposit for a room aboard the Titanic. Hershey, of course, never took the trip.

"This is one of the few places that actually still exists around the industry that it was founded," said Spokeswoman Amy Bischof. "And he didn't just build a place for people to work, he built a place for people to live."

Gary Forgione says this is the second time he and his family have visited Hershey. Why did he come?

"Chocolate," he said. "No, it's how they make it and everything. I like the museum more than anything."

The museum, in particular, is bursting at the seams. Bischof says it's time for a new, modern space.

"It's a very difficult place in which to house exhibits, high ceilings, and the acoustics are difficult to work with," Bischof said.

The museum is offering a free admission on its final day as a way to say thanks to the people who have come to Hershey, and those who keep coming back.

On Tuesday, the historic museum will be closing its doors for good. But come January, a new museum featuring much more on the history of chocolate will be opening.
