Bower (The Secret of Novice Hame)

On the last day of Novice Hame's life, the people of New Earth built her a bower on the clifftops, overlooking the New Atlantic.

There, she was visited by the Tenth Doctor, who was also dying himself. He told her stories of his travels after they had last met, and Hame intended to tell him a last secret, but died before being able to do so. (WC: The Secret of Novice Hame)
