Batanes The outpost of the Philippines in the middle of a turbulent sea, Batanes province comprises the northernmost isles of the Philippines. The island of Y'ami is only 224 kilometers from Taiwan. The Balintang Channel, where the Pacific Ocean and China Sea meet, separates the islands from the rest of Luzon. The three major islands of Itbayat, Sabtang and Batan, are the only inhabited islands of the small archipelago. About half of its area is hilly and mountainous.

Typhoons on a northwesterly path regularly sweep through the islands from July to October although rainfall is heaviest from August to November. Batanes, as a whole, enjoys a pleasantly cooler climate because of its greater distance from the equator. From December until February, temperatures may dip as low as 7 degrees Celsius.

The Ivatans lived in relatively well-populated settlements at the time western travelers visited the islands. William Dampier, an English buccaneer, visited Batanes in 1687 and found the people organized into communities built around protected settlements called idjangs, which were usually defensive positions on top of steep hills.

The Dominican friars attempted to Christianize the Ivatans as early as 1686 but the efforts were abandoned with the death of two resident missionaries. In 1718, missionaries made another attempt to bring the people of Batanes under the Cross. Missions directed from the island of Calayan in the Babuyan Group were sent to Batanes to urge the residents to resettle in the Babuyanes.
