The legendary castle has been painted emerald for people under 147 centimeters tall. Last night, Wales' famous Cardiff Castle was bathed in an emerald glow. This is how the authorities supported the International Dwarf Awareness Day, celebrated on October 25. Dwarfism (usually achondroplasia) is a genetic trait in which the height of an adult does not exceed 147 centimeters. The emerald hue has become the official symbol of a global campaign to protect the rights and draw attention to the problems of people with this diagnosis.
