The National Maritime Museum is a huge place for learning about the sea. 

The museum holds more than two million different items. These items tell stories about British history on the ocean. You can see beautiful maritime art and old maps. There are also ship models and very detailed plans. The collection includes scientific tools used for navigation. Some tools are used to tell time or study the stars. 
Greenwich has a very long history with the sea. Romans used this area as a place to land their boats. King Henry VIII also lived in this area. In 1675, King Charles II started the Royal Observatory nearby. This helped people find their way using the stars. Greenwich is also home to the Prime Meridian. This is a special line used to set time around the world. Because of this, Greenwich is a center for studying space and time.
The museum was officially started by a law in 1934. A man named Sir James Caird gave many donations to help. Because of his help, the museum could truly begin. King George VI opened the museum on April 27, 1937. His daughter, Princess Elizabeth, went with him on a boat trip. The first person to lead the museum was Sir Geoffrey Callender. 
Sometimes, the museum has difficult stories to tell about its items. After World War II, the museum got items from a German naval school. These included flags, paintings, and ship models. Some people have called these items looted art. The museum calls them war trophies from the Potsdam Conference. 
The National Maritime Museum (NMM) is a major institution dedicated to maritime history. 
The museum's collection is massive and diverse. It contains more than two million individual items. These holdings include maritime art, such as British and 17th-century Dutch paintings. 

Greenwich has been a center for sea-related activities for a very long time. The Romans used the area as a landing place. Later, King Henry VIII lived in the area. In 1675, King Charles II founded the Royal Observatory. The goal was to help people find the longitude of different places. Since 1884, Greenwich has been the home of the Prime Meridian. It is also the home of Greenwich Mean Time. Because of this, navigators worldwide use Greenwich time to set their clocks. This makes the area a global center for astronomical study.
The museum was officially established by the National Maritime Museum Act 1934. It was managed by a Board of Trustees appointed by HM Treasury. Much of the museum exists because of Sir James Caird. He was a major donor who provided many generous gifts. King George VI formally opened the museum on April 27, 1937. He traveled along the Thames with his daughter, Princess Elizabeth. Sir Geoffrey Callender served as the museum's very first director. To honor the founder, the museum awards the Caird Medal annually. This award recognizes people who do important work in maritime interests. 
The museum's history also involves complex discussions about how items are acquired. After World War II, the museum received items from the German Naval Academy Mürwik. These items included flags, paintings, and ship models. Some critics have described these pieces as "looted art." The museum describes these objects as "war trophies." They were removed under the rules of the Potsdam Conference. This highlights how history can be viewed in different ways. Managing such collections requires careful study of international agreements and historical events.
The museum buildings have also changed over time. The museum was first established in 1934 in Greenwich Park. It originally occupied buildings used by the Royal Hospital School. In 1999, the main galleries underwent a major redevelopment. This project centered on Neptune Court and was funded by the Heritage Lottery Fund. In 2008, the museum received a £20 million donation from Sammy Ofer. This money was for a new gallery. More recently, a large refurbishment was completed in 2025. The main gallery was renamed the Ocean Court during this process.
In recent years, the museum has been involved in major efforts to save history. In 2018, a group of museums formed a consortium. This group included the NMM, Titanic Belfast, and others. They wanted to buy 5,500 relics from the bankrupt Premier Exhibitions. These items were related to the Titanic. The goal was to keep the artifacts together as one exhibit. The oceanographer Robert Ballard supported this plan. He believed the items should be displayed in both Belfast and Greenwich. Although the group faced funding challenges in a Florida court, the effort showed deep dedication to maritime heritage.
