History
The Denes were an extensive beach area on the east side of the walled town. Townsmen let their animals roam here. Also in the area are windmills that had been built since the time of Edward I, and were a source of complaint by the Cinque Ports men, who charged that they interfered with the drying of fishing-nets. In 1277, Edward ordered a limitation on the number of windmills there. This right to dry their nets there was part of the rights of "den and strond" granted the Cinque Ports men by Henry II; the nets were hung from ships' masts.

The beach at North Denes was also used as an area for building ships, while old, derelict ships abandoned there was another source of annoyance to the Portsmen.
