This 1975 Greek commemorative stamp depicts the historic Church of the Holy Apostles (Agioi Apostoloi) in Kalamata, closely associated with the proclamation of the Greek War of Independence on 23 March 1821. The design highlights the distinctive Byzantine architectural form of the church, rendered in muted earthy tones against a soft blue background. Issued to honor a pivotal national historical moment, the stamp is a meaningful addition to collections focused on Greek independence, historical monuments, or religious architecture. Well-centered examples with intact perforations are especially desirable among thematic collectors. A classic mid-1970s Greek commemorative with enduring historical appeal.
