Tanapag Harbor

Tanapag Harbor (15.22667°N, 145.73667°W) is the primary harbor of Saipan, and is located on the western side of the island. It is separated from the Philippine Sea by a barrier reef, located about 3 km (2 miles) off the shore. This reef forms the Saipan Lagoon.

During World War II the harbor was occupied and used by Japan and later the United States. Following the war the harbor facilities have been significantly expanded to provide support for the U.S. Navy.

This port is also called Puetton Tanapag, or the inner harbor.

The harbor should not be confused with the similarly named popular introductory SCUBA diving site at Tanapag Beach. Dive_sites_of_saipan
