It is named after Saint Agatha, on whose feast day 5 February, Pope Clement XII reestablished the sovereignty of the republic in 1740.

The central disc bears a painted image of Saint Agatha, the Orders namesake, surrounded by a white-enamelled ring.

The ring bears the words; "SANT AGATA PROTETTRICE" (Saint Agatha Protector), while the bottom has a gold laurel wreath.

The reverse of the badge shows a gold representation of the Coat of Arms of San Marino, surrounded by the Orders motto: Bene Merenti.

[29] The ribbon is made up of the three colours, with a larger field of burgundy in the center, edged with smaller bands of white and orange on both sides.
