FANZARA, SPAIN - Fanzara is a small Spanish country village whose handful of mostly elderly residents were once so bitterly divided that their allegiance to one camp or the other determined which bar they frequented.

So heated became the local tussle over plans to build a toxic waste dump that it aroused old Civil War-era rivalry and prompted neighbors to cross the street to avoid one another.

But, today in Fanzara, the bad blood is almost forgotten and the village has been revived, thanks to street artists from around the world.

Tourists now flock to admire giant murals created by invited urban artists on the sides of buildings in the village, which has become an open-air art gallery.

To the chimes of the village bell and dogs barking in the distance, Fanzara, some 80 kilometres north of the eastern port city of Valencia, has become a living canvas for colorful artwork.

A three-wall picture depicts a robot with long, thin arms chasing cats, while another nearby mural features a creature with large white eyes holding a tiny planet in its hand.

"We looked for an arts and culture project that everyone could take part in and that would reestablish good relations among villagers," said former municipal councillor Javier Lopez, one of the project's architects.

For years, residents of Fanzara - 70 percent of them pensioners - had been at loggerheads over the waste incinerator proposal.

It was defeated in the end and the right-wing municipal council promoting the project was swept from power in 2011 elections.

But locals say tensions remained long after the plan was dropped, with supporters drinking in the village's "upper bar", while opponents, who were concerned about the incinerator's environmental impact, preferred the "lower bar".

"We would know what side you were on depending on which bar you went to," said Marc Zapata, a 22-year-old firefighter seated at a table in the "upper bar".

The feud even stoked old divisions between left- and right-wing families dating back to Spain's bloody 1936-39 Civil War.

So in 2014 the village's new municipal council came up with the idea to invite local residents and street artists to create one giant mural.

It turned into a street art festival, with 21 artists descending on Fanzara a few months later who ended up decorating dozens of gray walls encouraged by enthusiastic locals. Some could be seen hoisted on cranes as they painted the walls.

Since 2015 more than 2,300 children have taken a guided tour of the works, helping to invigorate the life of the village that is home to just 18 schoolchildren.

Fanzara now has 105 works and many residents have embraced the festival. More than 200 artists from around the globe have already applied to take part in its next edition, from July 6 to 9.
