Mental_floss kicks off their monthly "lists of 11 on the 11th" with tautological place names. That means they're redundant, using two or more terms that mean the same thing. An example is Pendle Hill in Lancashire, England.
The Pendle in Pendle Hill is derived from Pen-hyll, a combination of the Cumbric word for hill and the Old English word for hill. So Pendle Hill is really Hill Hill Hill.
