(CNN) — Italian photographer Valerio Vincenzo has spent the last eight years photographing the EU's internal boundaries: that's 26 countries and 16,500 kilometers of borders that can be freely crossed.

His serene images of abandoned customs houses and quiet beaches and woods raise questions about the authenticity of geographical boundaries and national identities.

His project "Borderline, the Frontiers of Peace" will be exhibited at the UNESCO headquarters in Paris in September.

He recently spoke with CNN about his project and desire for a "pre-1914 Europe" free of border controls.

Photographer Valerio Vincenzo Mehrak

CNN: Europe's Schengen Agreement is a pretty strange inspiration for an art project, isn't it?

Valerio Vincenzo: The Schengen Agreement led to the creation of the Schengen Area, which since 1995 has allowed Europeans to freely travel, live and work in many EU countries -- 26 as of today.

This was inconceivable during the Cold War and is probably the most important historical event in Europe since World War II.

I wanted to give visibility to this radical change.

CNN: Border zones aren't particularly photogenic, are they?

Vincenzo: I show images that are very different from what we tend to associate with the notion of borders: fences, barbed wire, patrols.

By showing very calm, peaceful border landscapes, I question the meaning nowadays of borderlines between countries.

I want to talk about the borders of the future, more than about the borders of the past.

CNN: Which was the first photograph in the series?

Vincenzo: The first was shot in 2007 and shows the customs house between France and Belgium, which has been converted into a chocolate shop.

When I started, I was interested in showing all the abandoned customs houses, but soon became more intrigued by landscape images of the borderline.

CNN: You used a 1964 Hasselblad with a 50mm lens. Why go vintage?

Vincenzo: I needed a sturdy camera that does not need batteries to work and that can produce an image with a very high resolution.

I also like the fact that each roll of film I use only has 12 pictures.

The less pictures I can shoot, the more I think before shooting!

“I want to talk about the borders of the future, more than about the borders of the past. ”

CNN: Do you have a favorite picture?

Vincenzo: The image of the border between Italy and Switzerland with the snow.

I like its simple and essential composition.

CNN: What opportunities have you enjoyed as a self-described member of the "Schengen generation"?

Vincenzo: I was born in Italy, I lived in France for the past 10 years and acquired French nationality, and now I am based in the Netherlands.

Without having to do any paperwork at all, I cannot only travel but also live and work at any time in any of the 26 countries of the Schengen Area.

I still remember when I first moved to France in 1993, just before the Schengen Agreements: getting a residence permit was a nightmare.

CNN: The freedom to cross EU borders has been challenged by the current migrant crisis in Europe, particularly in your home countries of France and Italy.

Vincenzo: The temporary checks at the French-Italian border and the wall between Greece and Turkey, as well as the fences of the Spanish enclave of Melilla or the projected fence between Hungary and Serbia, make me sad and ashamed.

I think that we should learn from history; it has a lot to teach us.

Barriers between countries and walls between people might give the impression they solve the situation in the short term, but they actually have never been a long-term viable solution in Europe, as well in the rest of the world.

CNN: What's the solution?

Vincenzo: As Stefan Zweig recalled in his "World of Yesterday," before 1914, there were no passports, visas, permits or authorizations required, and everyone could freely travel around the world.

I know this sounds utopian nowadays, just as the Europe that I show in my pictures sounded utopian less than 50 years ago.

I strongly believe we should work today towards a pre-1914 free liberty of movement for everyone.

This should be a basic right of every individual.

CNN: A lot of your photographs feature people you met by chance along the borders.

Vincenzo: I met many people during this project.

I heard many stories linked to the former existence of borders: stories of families or couples split in two, stories of smuggling and stories of the adventurous lives of the former customs officers.

Collecting these stories is a whole other job that I hope somebody will do or is doing at the moment.

CNN: How was your recent trip to the edges of the EU?

Vincenzo: I traveled along the EU borders of Croatia and Romania.

From 2007 to 2013, I crossed Schengen borders more than a thousand times without ever having to show my ID, but on this trip, I was stopped by border controls numerous times.

I had the unpleasant impression of jumping back into a surreal and irrational past.
