"Now everyone from the Castellon region can also enjoy Ryanair flights at the first privately operated airport in Spain," said the company's marketing manager, Jose Espartero.
It would be unfair to say that Castellon airport has not been used at all since 2011. The Villarreal football team sometimes uses it when chartering flights to play away games, although as some have pointed out, the club's shirt sponsor used to be none other than Castellon airport itself.
Castellon is one of a number of building projects that fell victim to developers going out of business, running out of funds or not appreciating that their masterpiece was not needed during the boom years.
Another airport, in Ciudad Real, remains unused despite costing more than €1bn to build. Airlines did use it, but left when the company managing it went bust.
In Benidorm, what was supposed to be Europe's largest block of flats - the 200m-high Intempo - has just been completed after taking more than eight years to build.
In the 1990s, Spain's regions were told by Madrid to embark on projects that would set them apart from each other and encourage tourists to visit places other than the Costas - as part of the project, Bilbao built the Guggenheim.
Other ideas fell into trouble when the availability of cheap financing ran out. In Valencia, the City of Arts and Sciences, a building modelled on the Sydney Opera House and designed by Santiago Calatrava, was originally supposed to cost €300m ($433,96), but years over budget, the eventual price tag was €1.1bn ($1.59bn)
While projects such as Castellon airport attract attention, many other buildings - mostly housing blocks - sit unfinished and uninhabited across Spain.
With an economic recovery slowly gaining traction it is hoped that new developers finish some of these projects, but like the airport, many were not wanted, or needed, in the first place.
