The pieces on display are just the tip of the iceberg in any museum; the vast majority of the collection is stored in the reserves.
In addition to the collections storage of the Manuel Coelho Baptista de Lima Military History Centre, which are open to the public every two months, the Museum of Angra do Heroísmo has other thematic collections storage areas, such as this painting collection storage.
At times, the pieces that form part of the collections storage of the Museum of Angra do Heroísmo are loaned to other museums in the Azores for thematic exhibitions and may also be displayed in temporary exhibitions organised by the Museum.
