Sigri is a small fishing village near the western tip of Lesbos Island. Its name derives through Greek σίγουρος from the Venetian word siguro, meaning "safe", based on the fact that it has a safe harbour. Sigri has a Turkish castle, built in 1746 during the Ottoman occupation, which looks over the bay and the long island of Nissiopi, which stretches across the mouth of the bay and acts as a buffer to the prevailing winds. The port of Sigri is able to accommodate large vessels, even cruise ship-size ferry boats coming from the mainline. Almost all shipping to Lesbos, however, comes into the east of the island.
