The Roundhouse at Alyeska is the only mountaintop museum and interpretive center in the entire state. The original structure was built in 1960 and served as a warming hut and later as a popular gathering place in the mountain complete with lounge and restaurant. Renovations on the Roundhouse began in 2003 to turn it into the interpretive center and museum; today, visitors will be able to view various photographs taken from 1896 to 1904 in the permanent James Girdwood Collection. Other events that take place in the structure, which is listed on the National Register of Historic Places, include author visits, book signings, readings, and much more.
