<P> The flag that flew during that episode in history became a significant artifact . It remained in the possession of Major Armistead, who was promoted to brevet lieutenant colonel, and his family for many years . Eben Appleton, Colonel Armistead's grandson, inherited the flag in 1878 . In 1907, he lent it to the Smithsonian Institution, and in 1912 it was made a formal gift . Today it is permanently housed in the National Museum of American History, one of the Smithsonian Institution museums on the National Mall in Washington, D.C. The flag was given to the museum in 1912, and has undergone multiple restoration efforts after being originally restored by Amelia Fowler in 1914 . </P> <P> Due to environmental and light damage a four phase restoration project began in May 1999 . In the first phase, the team removed the linen support backing that was attached to the flag during the 1914 restoration . The second phase consisted of the most comprehensive, detailed examination of the condition and construction of the Star - Spangled Banner to date, which provided critical information for later work . This included scientific studies with infrared spectrometry, electron microscopy, mechanical testing, and determination of amino acid content by a New Zealand scientist, and infrared imaging by a NASA scientist . Planning and executing a cleaning treatment for the flag following scientific analysis was the third phase . In the fourth and final phase of the project, curators, scientists and conservators developed a long - term preservation plan . The restoration was completed in 2008 at a total cost in excess of $21 million . </P> <P> Following the reopening of the National Museum of American History on November 21, 2008, the flag is now on display in a two - story display chamber that allows it to lie at a 10 - degree angle in dim light . The Smithsonian has created a permanent exhibition to document the flag's history and significance, called "The Star - Spangled Banner: The Flag that Inspired the National Anthem". Visitors are allowed a clear view of the flag, while it remains protected in a controlled environment . </P> <P> The National Museum of American History produced an online exhibition in conjunction with the reopening of Flag Hall in 2008 . An interactive component allows site visitors to closely explore features of the flag in detail, download an audiodescriptive tour of the exhibition for the visually - impaired, and hear the song performed on original instruments from the National Museum of American History's collection . </P>
