EFEOviedo (Spain)

The Spanish prosecutor's office on Thursday asked that the former director of a cultural center designed by and dedicated to an iconic Brazilian architect be handed an 11-year prison sentence for alleged corruption.

Natalio Grueso is under official investigation for suspected embezzlement and forgery of commercial and corporate documents while he was the director of the Oscar Niemeyer International Cultural Center located in the northwestern Spanish town of Aviles.

The prosecutor's office, which has already submitted the petition to the investigating court, also asked for sentences of between 18 months and eight years for the other four people who stand accused.

The case was initially opened in order to investigate alleged irregularities in the accounts of the Center, which at the time was run by Grueso.

Also being investigated are the former head of production at the Center, Marc Marti, the former secretary Jose Luis Rebollo, Grueso's ex-wife and a travel agent.

The cultural center was one of Niemeyer's final architectural projects before his death in 2012 at the age of 104.

The complex features smooth round shapes painted white, with pops of bright red and yellow, and a screw-like viewing tower with exterior stairs.
