The town was a considerable port in the 19th century , but was completely destroyed by the 1883 eruption of Krakatoa . The present settlement still houses the Cikoneng Lighthouse built by Dutch government two years later as a memorial for the townspeople killed by the eruption . It was also the starting point of the Great Post Road , built by the Dutch in the nineteenth century , which ran around to the eastern tip of Java . Off the coast of Anyer is the island Pulau Sangiang , an uninhabited island with vast areas of untouched jungle . The area is also known for coral formations swarming with tropical fish
