The museum remained under the Department of Public instructions until 1965 when it became the responsibility of the Department of information, Cultural Affairs and Tourism. In 1981 this detached to form the National Bureau of Culture & Tourism of which the museum operated under through much of the 1980s until June 1987 when it was dissoluted and returned to the control of the Department of Information.
In 1972, the museum was relocated to a new building on Providence Island but four years later this building was removed to facilitate the construction of the People's Bridge over the Mesurado River.
It was later moved to the Old Supreme Court building and formally reopened on July 25, 1987 with a ceremony given by the Vice President of Liberia, Harry F. Moniba.
The museum is classified in three tiers, where on the ground floor there is a histographical gallery containing presidential papers, private documents and memoirs of past important executives of the Liberian government and photographs and cartographical resources related to its culture. On display is the nations first flag dating back to August 1847. There are also other items ranging from postage stamps to an editorial page of Liberia's daily newspaper, the Liberia Herald. Other items include traditional Liberian household furniture and utensils, and there is a craft shop run by the African Arts & Crafts Inc.
On the next floor is the Ethnographical Gallery and on the top floor the contemporary arts gallery which illustrates Liberian artistic works many of which are product of a contract between the museum and art institutions and art colleges throughout the country where artists are commissioned to produce for the museum purposes.
Other museum facilities include a portable video system, editing and archival materials, cassette recordings and slides of visual and oral arts many of which offer an insight into Liberian cultures such as dance and the use of masks in the country.
Effects of the Liberian civil war
The national museum was deeply affected by the 14 years of war during the Liberian Civil War. According to the director of the museum Caesar Harris approximately 5,000 artefacts were looted during this period and now less than 100 larger artefacts remain. Still intact though is a 250-year-old dining table given as gift from Queen Victoria to Liberia's first President, Joseph Jenkins Roberts. During the war, valuable museum items were often sold to fleeing expatriates and the museum itself came under fire during rebel attacks in 2003. However, although the war severerly affected the content of the museum today it also has items which offer an insight into the war itself.
