Since the removal of the first moai Hoa Hakananai'a from Easter Island in 1868 by the crew of HMS Topaze, 79 complete moai, heads, torsos, pukao, and moai figurines are also known to have been removed from their original sites, and transferred to either private collections, the collections of museums (including the Museo Arqueological Padre Sebastian Englert on Easter Island), or, most recently to the university grounds of the American University, Washington D.C. in 2000. Some of the moai have been further transferred between museums and private collections, for reasons such as the moais' preservation, academic research and for public education, or – in the instance of the moai from Centro Cultural Recoleta – for repatriation after 80 years overseas.
