Portland Bill is a narrow promontory (or bill) at the southern end of the Isle of Portland, and the southernmost point of Dorset, England. One of Portland's most popular destinations, the popular attraction Portland Bill Lighthouse is found in the area. Both Portland Bill and Chesil Beach are the locations of many wrecks of vessels that failed to reach Weymouth or Portland Roads. Portland Bill is also noted for its rough coast, and is the only place on Portland where the limestone cliffs rise directly from the sea. As such many landforms including coves, ledges and caves have been formed.
