The foundation stone for the third golden tower of the European Court in Luxembourg was laid on Monday.

The building will be 15 metres taller than the existing two towers, making it the tallest building in Luxembourg when it is completed in July 2019.

Ground work began at the site on the Kirchberg plateau in March this year. Monday’s stone laying was a symbolic act which “reaffirms our faith in the stability of the European Union,” Court of Justice President Koen Lenaerts said, referring to the political turmoil created by last week’s UK referendum outcome.

This new tower marks the fifth expansion of the court, which has grown in step with the enlargement of the EU.

The new tower was designed by French architect Dominique Perrault.
