The capital that was rebuilt 40 times

Lying at the confluence of the mighty Danube and Sava rivers, Belgrade has a long and tumultuous history that goes back some 7,000 years.

Vibrant and full of character, the Serbian capital is today home to some 1.5 million people.

Although it has enjoyed peaceful periods throughout its history, Belgrade has been destroyed and rebuilt around 40 times.

In 1999, the city was hit by a NATO air campaign. The targets included the former federal military headquarters in Belgrade (pictured here still destroyed earlier this year).

Today Belgrade is stepping up its efforts to rebuild once again. Pictured here, construction work of a new bridge over the Danube on July 23, 2013.

Savamala is one of Belgrade's oldest neighbourhoods. Once ugly, industrial and neglected, the area has lately become the city's cultural heartbeat.

Mikser House is at the epicenter of Savamala's creative revival. Housed inside a renovated garage, the space is now a thriving hub showcasing the best of Balkan design, thought and food.

Street markets are also a big part of life in Belgrade. Pictured here is a vendor selling jars of homemade "Ajvar," a type of relish mainly made from roasted red bell peppers.

Belgrade, or Beograd, which means "white fortress," grew up around a centuries-old fortress on the Kalemegdan headland overlooking the point where the Danube and Sava rivers meet.

Today the fortress is a historic monument and a popular tourist destination attracting visitors from around the world.

Filled with profound relics of the city's past, the Belgrade Fortress also boasts several archaeological treasures.

(CNN) -- In the heart of Belgrade, the vibrant and resilient capital of Serbia, a slow and colorful transformation is taking place.

Once ugly and industrial, the historic neighborhood of Savamala has emerged in recent years as the thriving epicenter of the city's cultural life. Following decades of neglect, Savamala is now blossoming back to life as a diverse crowd of artists and entrepreneurs have poured in to reclaim the area and transform its run-down warehouses and abandoned spaces into hubs of creativity.

At the center of this urban remake is Mikser House, a previously derelict state-owned garage that has now become a booming cultural space showcasing the best of Balkan art, thought and design.

"It's a roof for many different activities," says Maja Lalic, the creative force behind Mikser House. "It's basically connecting creative people of very different disciplines but with a similar goal and desire to be productive and constructive," continues Lalic, an Ivy League-educated architect.

"These small-scale skills of surviving and being able to make something out of nothing, this kind of bitter-sweet attitude to life, and we used to say 'who if not us,' and 'when if not now.'"

Rich history

Such a transformation is not new in Belgrade, a city that has been destroyed and rebuilt some 40 times throughout its long and tumultuous history.

Lying at the confluence of the great Danube and Sava rivers, Belgrade -- home today for some 1.5 million people -- is strategically located at the crossroads between Eastern and Western Europe and a meeting point of different civilizations.

The perseverance of Belgrade

Nowhere is Belgrade's historical and cultural significance more evident than in the imposing ancient fortress that towers over the point where the Danube and Sava rivers mingle.

Standing in some form since the second century on top of a cliff-like ridge, the sprawling castle has over the years sheltered Serbian, Roman, Byzantine and Ottoman troops -- to name just a few.

"Belgrade was so many times conquered, pulled down and built again, so, that is why we have so many layers and every of those people left its marks on the ground of this city," says art historian Bojana Ibrajter Gazibara, surrounded by a cluster of ancient statues and elaborate headstones that dot an old gunpowder storage room deep inside the fortress.

Breathtaking scenery

Now a historical monument that encompasses a large park, the fortress is a popular destination for locals and tourists thanks to its charming walking paths and spectacular river views.

It's also the ideal location for Dragan Trifunovic, the owner/pilot of Helivideo, who often comes here to fly his camera-mounted drone and capture Belgrade's grand picture -- as well as its continuous rebuilding.

"When I was kid I always dreamed how it would be nice to be able to fly and to see what birds can see, and with this equipment, my dreams came true," says Trifunovic, adding that the breathtaking shots give people more pride in their city.

"People are very proud to live in this city and to see it from another angle," he says.
