The ceremony marks the 25th anniversary of the Prize and will be held at the Mies van der Rohe Pavilion in Barcelona. The winners of this year´s main prize are Henning Larsen Architects, Studio Olafur Eliasson and Batteríið Architects for Harpa, the Reykjavik Concert Hall and Conference Centre in Iceland.

The Emerging Architect Special Mention award goes to María Langarita and Víctor Navarro for the Nave de Música Matadero (Red Bull Music Academy), which was built to host a music festival in Madrid.

"The ´story´ behind the Harpa building is inspiring. Started shortly before the economic crisis engulfed Iceland and Europe, the building could easily have become a symbol of collapse. Instead, the government and city of Reykjavik were determined to finish the job.

Harpa has become a symbol of hope and renewal, receiving nearly 2 million visitors since its opening in 2011. It is a great example of how investment in the cultural and creative sectors can create jobs and wider economic, social and cultural benefits. I hope the Harpa story will encourage more public and private investors to support the immense talent that we have in European contemporary architecture," said Androulla Vassiliou, European Commissioner for Education, Culture, Multilingualism and Youth.

Jan Truszczyński, the Commission´s Director General for Education and Culture, and Xavier Trias, Mayor of Barcelona, will present the winners with prizes of €60 000 (main award) and €20 000 (emerging architect). The winners will also receive sculptures by the Catalan artist Xavier Corberó.

The ceremony will be followed by the opening of an exhibition, Constructing Europe, 25 Years of Architecture, at the Museu Nacional d´Art de Catalunya. It features models of 200 of the buildings short-listed for the Prize since 1988, showcasing the breadth and quality of Europe’s contemporary architecture over the past 25 years.
