“Fragments,” a work in iron wood and pillars from the dismantled temples of the Qing Dynasty, will be installed in a section of the national Asian art museum dedicated to contemporary work. Ai’s installation will open May 12 for one year as part of the Sackler’s 25th anniversary.

Ai, 54, is perhaps the most famous critic of China’s human rights positions and government policies which he has called “ruthless.” Last year he was detained for three months by the government.

The artist will also be highlighted in “Ai Weiwei: According to What?”at the Hirshhorn Museum and Sculpture Garden, beginning in October. Both museums are hopeful Ai will be able to visit the shows. “All I know is late June is the end of his term of remaining in the country,” said Carol Huh, the assistant curator of contemporary Asian Art at the Sackler. She said two of Ai studio assistants and carpenters will install the piece.
