Natalie Barney was famous for her literary salons in the 1920s that rivaled Gertrude Stein's.
In fact, James Joyce refused to attend Stein's but was often seen at Barney's.
Hemingway was often a frequent visitor here as well.

It is behind this apartment building that Natalie Barney's pavilion
stood and next to it her Greek "Temple of Friendship".
