The Arms Museum of Eibar houses the arm collection originally belonging to the Arms Museum located since 1914 in the Armery School, as well as latter purchases and donations.

The collection has approximately 500 pieces, consisting of small and large firearms and steel weapons, the former of which are by far the larger proportion. The pieces come from Eibar and from abroad, and though the vast majority of items on display are from the 19th and 20th centuries, the oldest exhibit dates from the 16th century.
