Oval chapel from the 19th century, on the obverse an engraved image of Our Lady of Czestochowa, faces, hands and vestments painted in oil paints. In the rim a Latin inscription: "TERRIBILS , VT CASTRO , RVM , ACIES , ORDINATA" (a quotation from the Song of Songs, read as a symbol of Mary's strength as Protector and Queen).
The reverse depicts a crowned eagle with outspread wings, head to the right, holding in its beak a ribbon with the inscription: "REGINA POLONIAE". The eagle stands on a beam with the inscription: "MISERERE MEI". This sentence, which translates as "Queen of Poland - have mercy on me," is a reference to the Virgin Mary and a prayer invocation of a supplicatory and penitential nature. Juxtaposed with the Eagle, it has a patriotic character, which is emphasized by the form of the object. Caplers, which are oval or rectangular images painted on tin, usually copper, were worn by soldiers in the 17th and 18th centuries. They were particularly popular during the Bar Confederation. The chapel was made of silver-plated sheet metal (brass or alpaca), the edge finished with a simple ferrule with an eyelet for hanging.
