The importance and mission of Lithuania’s defence can be characterised by the following key elements: territorial integrity, safeguarding interests by protecting and promoting the country’s independence, and an active role in contributing to regional and international security which helps to find unity with the community that protects and upholds common values. The anti-tank barrier, also known as the Czech hedgehog, serves as a symbol and tool, as well as a reminder that freedom is a result of the strength of the nation’s spirit, while readiness to defend oneself sends a message that the country and every citizen has both the right and the opportunity to contribute to creating a free Lithuania in a free Europe and a free world. The national side (the obverse) of the commemorative coin dedicated to defence features the contours of Lithuania. The state borders are surrounded by a stylised spine barrier, symbolising the concept of holistic and whole-of-society defence. The image of the hedgehog also represents the openness and fragility of free societies, which must be defended, to the utmost, against external threats. Lithuania is presented as a hedgehog that remains at the ready to defend itself always. The centre of the obverse bears the inscription “LIETUVA” (LITHUANIA), the year of issue (2025), and the mintmark of the Lithuanian Mint. The coin’s outer ring bears the 12 stars of the EU flag.
