Freshwater
Freshwater is a big town as well as civil parish at the western end of the Isle of Wight, England. Freshwater Bay is a small cove on the south coastline of the Island which also gives its name to the neighboring part of Freshwater. Freshwater rests at the western end of the area known as the Rear of the Wight or the West Wight which is a preferred vacationer area. Freshwater is close to high chalk high cliffs. It was the native home of physicist Robert Hooke and also was the residence of Poet Laureate Alfred Lord Tennyson. Freshwater is renowned for its geology as well as coastal rock developments that have arised from centuries well worth of coastal erosion. The "Arch Rock" was a popular regional spots that fell down on 25 October 1992. The neighbouring "Stag Rock" is so called since apparently a stag jumped to the rock from the high cliff to escape during a search. An additional substantial piece diminished the high cliff face in 1968, as well as is now referred to as the "Mermaid Rock". Promptly behind Mermaid Rock exists a little Sea cavern that reduces numerous metres right into the brand-new high cliff.
