Gathering this collection began in the second half of the 19^th century, following the decree given by Prince Alexandru Ioan Cuza which stated the storage of out-dated weapons and colours within the Army’s Arsenal. The elements thus collected were first displayed in the Artillery Museum in 1893, near the Army’s Arsenal. Sadly, these pieces were lost during the occupation of Bucharest, in the Great War, by the Central Powers’ armies.

After the war, regathering the collection started, which grew year after year, today having a total of 1049 items, out of which 956 cannons and howitzers, 78 various accessories, 650 munition elements and 15 firing conducting machines.
