A type of bullseye, called a roundel, is used on military craft.
A French military roundel consists of three concentric circles: a red outer ring, a blue inner dot, and a white ring separating the two.
The modern-day U.K.'s Royal Air Force still uses a roundel as its insignia.
This is now replaced by a roundel which did not show the fineness of the workmanship found in the tower.
The roasted sweet pepper awash with garlic provided a vibrant backdrop to a large roundel of goat's cheese oozing over its crostini perch.
