Flag of Londonderry Ireland - Color Changing Coffee Mug

The Flag of Londonderry, also known as the Foyle Flag, is a symbol associated with the city of Londonderry (or Derry) in Northern Ireland. This banner features three vertical stripes: red on the hoist side, white in the middle, and blue on the fly. The red represents the blood shed by the defenders of the city during its 1689 siege, while the blue symbolizes the River Foyle that flows through Derry. The white stripe serves as a peace dividing the two colors. The flag is often associated with the Apprentice Boys of Derry, a historical society commemorating the apprentices who defended the city during the siege. Its use extends beyond the city itself and has significance in local culture and identity within Northern Ireland.
