The port municipality of Guinsiliban is home to the antiquated Moro tower - built by the Spaniards to guard against raids from the Moro people of Mindanao.
Guinsiliban used to have a good trading relationship with the neighboring Asian countries before the arrival of the Spaniards. It was also the central settlement of Camiguin under the rule of Sultan Kudarat. It use to be constantly raided by Moros from neighboring provinces and the locals were forced to make an observation post where the children and women could hide during raids. It got its name from the Bisayan term of observation post, “guinsil-ipan.”
