While the main museum opened more than 15 years ago and the Ferry Building opened just this year, almost 30 other buildings are spread across Ellis Island. They are in varying states of deterioration, as stabilization and restoration efforts are moving slowly.
More than 12 million immigrants passed through Ellis Island from the time it opened at the end of the 19th century until its closure in 1954. Among the buildings on the South Side being restored are two massive hospitals, administration buildings and the home of the Island's chief administrator.
