Nepal (नेपाल) has its flag red with a blue border around the unique shape of two overlapping right triangles. The smaller, upper triangle has a white stylized moon and the larger and lower triangle displays a white 12-pointed sun. The color red represents the rhododendron (the National flower of Nepal) and the color red is sign of victory and bravery. The blue border signifies peace and harmony; the two right triangles are a combination of two single pennons (pennants) that originally symbolized the Himalaya Mountains. The moon represents the serenity of the Nepalese people and the shade and cool weather in the Himalayas, while the sun depicts the heat and higher temperatures of the lower parts of Nepal. The moon and the sun are also said to express the strong belief that the Nepal will be there in the earth as long as Sun and Moon are in the sky.
Nepal is the only country in the world with triangular flag.
