In 1902, the sanitarium building burned, and its surviving blocks were used to build Grant-Lee Hall, which has since been placed on the National Register of Historic Places. Arthur's house also burned, but its tower, now called "Conservatory Tower," still stands. In April 1917, British folklorist Cecil Sharp spent several days at Lincoln Memorial University, where he collected 22 local versions of "old world" ballads such as "Lord Thomas and Fair Ellinor," "The Daemon Lover," and "Lady Isabel and the Elf Knight."
