This Irish 48-cent stamp, issued in 2005, depicts the Round Tower of Clones (Cluain Eois) in County Monaghan. Rendered in a delicate black-and-white line drawing, the design highlights the tall cylindrical stone tower—one of Ireland’s medieval monastic landmarks—beside an ancient tree and graveyard. Round towers like this were originally built between the 9th and 12th centuries as bell towers and places of refuge. The stamp celebrates Ireland’s early Christian heritage and architectural artistry.
