Telegraph Island, located in the Elphinstone Inlet near the Musandam Peninsula in Oman, was once home to a British repeater station built in 1864 for the Persian Gulf submarine cable. Abandoned in the mid-1870s, the island now stands as a reminder of the British Empire, with only ruins left behind. Today, it's a popular tourist spot, visited by dhows carrying tourists to explore the old station's remains and enjoy activities like fishing and snorkeling in the surrounding waters. The island's history and scenic beauty make it a must-visit destination for those exploring the Persian Gulf region.
