Plans to build an underwater branch of the Guggenheim museum here are dead in the water, Rio's mayor said on Thursday. "The first project offered lots of risks, even functional ones since it was a submerged museum," said Cesar Maia. Maia scuttled expectations for the museum, which he and Guggenheim director Thomas Krens announced with great fanfare in 2003. Expected to cost $170-million, the museum was designed by French architect Jean Nouvel and was supposed to anchor a larger project to revitalise the city's decrepit port district.
