Introduction

Launching of the Monitor

The wreck of the USS Monitor is perhaps the most famous in the United States. The site became the first Marine Sanctuary designated by the United States Government on January 30, 1975. Since that time, many research dives have been conducted in an effort to help preserve this historic landmark. The Cambrian Foundation is proud to be a participant in the efforts to preserve and protect this most fragile piece of American history.
