This summer, passersby gazing up at the National Gallery of Art’s East Building will see a giant rooster overhead. The nearly 15-foot-tall bird will be perched atop the museum beginning in July, two months ahead of the building’s reopening.

The electric blue sculpture, “Hahn/Cock,” was created by German artist Katharina Fritsch and first made public in London in 2013. After an 18-month-run, it was purchased by Glenstone, a private museum in Potomac Md., which in turn, is loaning it to the gallery.

“The relocation of this enigmatic monument from its original site in Trafalgar Square will add a surprising blast of color to one corner of the National Mall, while stimulating fascinating conversations about scale, context, nationality, and representation,” said Harry Cooper, the gallery’s curator and head of modern art, in a release.

Renovations of the National Gallery of Art’s 35-year-old East Building began three years ago, and are finally coming an end. Hahn/Cock will be the most grandiose work overlooking Pennsylvania Avenue in the museum’s new outdoor sculpture garden, which can also be used for people-watching on high with built-in seating.

The building’s latest additions also include a sky-lit fourth level with two tower galleries flanking the outdoor terrace. One of the new galleries will feature works by the late Alexander Calder, while the other will show a changing selection of paintings by the late Mark Rothko, along with other abstract expressionist pieces. The three new add-ons make up more than 12,250 feet of exhibition space. And to provide easier access to all levels of the building, a new elevator and stairs have also been installed.

The building will officially reopen on September 30 with a new configuration of the museum’s permanent collection of modern art.
