The photo below is of an old windmill ruin that used to operate atop peace hill. Ruins such as these are scattered throughout the island. Many of the trails throughout the island take you past the ruins of an era long gone on the island. These buildings were built as early as the 1700s as colonist settled the island and created a thriving sugar and rum industry. This era ended soon after the slave trade ended due to the fact that the slaves were the primary laborers for the sugar plantations on the island. Touring these ruins takes you back in time while visiting St. John and reminds you of a very important time in the history of this island.
