Celebrating the100th Anniversary of the Pontifical Institute of Christian Archaeology

On 11 December, exactly one hundred years after its foundation, the unveiling ceremony of the two commemorative stamps jointly issued by the Vatican City State and the Grand Duchy of Luxembourg took place at the Pontifical Institute of Christian Archaeology.

In 2025 the Pontifical Institute of Christian Archaeology marks its first one hundred years of activity, and the Postal and Philatelic Service of the Governorate of Vatican City State—together with Luxembourg, with which it is issuing a joint release—celebrates this anniversary with a postage stamp dedicated to a century of scientific activity and the safeguarding of Christian-era archaeological heritage.
