Abu Dhabi’s Louvre museum said on Sunday, November 13 it was commissioning renowned artists Giuseppe Penone and Jenny Holzer to create artworks to be displayed at its grand opening next year, AFP reports.

Designed by French architect Jean Nouvel and built at a cost of half a billion euros, the Louvre Abu Dhabi will feature 100,000 sq ft of gallery space.

The ambitious Louvre Abu Dhabi project, announced with much fanfare nearly a decade ago, has faced repeated delays. The museum was expected to open in December this year but has been postponed until 2017.

Built on the sea, promoters say Louvre Abu Dhabi will be a “museum city” which includes streets, waterways, and plaza with artworks displayed outside as well as inside the galleries.
