This Irish definitive stamp depicts the historic Ardmore Round Tower, one of Ireland’s finest surviving early medieval monastic towers. Round towers served as bell towers and places of refuge during Viking raids, symbolizing Ireland’s rich Christian heritage. Issued in 2005, the minimalist monochrome design highlights architectural detail and historical authenticity, making it attractive to collectors specializing in European architecture, religious heritage, or Irish definitives. The clean engraving-style artwork reflects Ireland’s modern definitive series aesthetic. A strong thematic addition for cultural and architectural collections.
