We're not going to leave you hanging any longer on today's Geo Quiz.

The answer is a city that's built behind dikes: the Dutch port of Rotterdam.

Rotterdam had to recreated itself after German bombers destroyed the Dutch port in World War II. The city's rebuilding efforts have been architecturally ambitious over the years. This summer, the city is celebrating some of its unique architecture in a multi-media project called Sites and Stories. Cyrus Farivar reports from Rotterdam on the interactive exhibit aimed at tourists.
When you ask Sites and Stories Program Director Anouk Estourgie for a tour of Rotterdam, she makes a beeline for her favorite french fry stand. Estourgie says the fry shop's name is well-known around Rotterdam Bram Ladage.

"Bram Ladage, that's the name of the owner of the shop. And in Rotterdam he's very famous for his French fries."

In fact, Ladage owns a chain of french fry places. There's even a famous jingle...in Dutch. The advantage of the Sites and Stories project is that you can listen to the jingle while you're standing in front of the fry shop. All you need is a listening device. Through the Sites and Stories website, you can download audio -- in Dutch and English -- about dozens of architecturally significant sites around Rotterdam before you head out on your tour. You can also use a cell phone to access the same recordings, or if you forgot your iPod and your cell phone, you can rent an audio device from the tourist office. The rental costs about ten dollars.

Your first question about Bram Ladage might be -- what's architecturally significant about a fry shop? Sites and Stories' Anouk Estourgie says that Ladage's flagship shop in the center of Rotterdam is actually one of the most unique buildings in town. She notes that it's essentially a large kiosk-sized metal box.

"It's one plate of steel, so per square meter it's the most expensive shop of Rotterdam. And it has a very large can of Pepsi Cola next to it."

And if you're wondering about the Pepsi Can -- just scroll to Location number 28 on your Mp3 player. You can hear Mr. Ladage himself explain.

" So I went to our supplier, Coca-Cola, to ask if, in exchange for advertisement on that enormous tin, they would share the cost. But they needed months to think about it, and eventually gave us nothing. So I went to their competitor and within a week, it was all arranged."

Around Rotterdam, Sites and Stories locations are marked with purple. When you see purple and the corresponding number, you'll know to switch on your audio.

Rotterdam's iconic Erasmus Bridge, for example, is swathed in purple light. As is one of the surreal Cube Houses designed by Dutch architect Piet Blom. Artist and self-described "city dresser" Madje Vollaers is part of a two-person team that came up with the artistic concept for Sites and Stories. She explains why purple was the color of choice.

"Purple was not adopted by anything and has no identity at all in the public space. Of course you've got the Catholics have something with purple, and the hippies have something with purple and James Brown has something with purple, but it isn't used in the public space. "

Metallic fry stands...cube houses...a bridge. It may sound like a strange line-up of sites to highlight in an audio tour of the city. But Project Director Anouk Estourgie says that these sites are part of Rotterdam's post-WWII healing process.

"Rotterdam is a city with a big wound in the center because of the bombing in the second world war and that makes it a very sepcial city because we don't have an old center. There are old parts, but the center is new. That's negative, of course, but it's also creating a lot of new possibilities. "

The Sites and Stories exhibit will be showing through late September. And those fries at Bram Ladage? They're available all year round.
