Azulejo is a form of Iberian painted tin-glazed ceramic tilework. They are an ornamental art form, but also had a specific function, such as aiding temperature control in homes.
There is also a tradition of their production in former Portuguese and Spanish colonies in North America, South America, the Philippines, Goa, Lusophone Africa, East Timor, and Macau. Azulejos constitute a major aspect of Portuguese and Spanish architecture to this day, and are found on buildings across Portugal, Spain and their former territories. Many azulejos chronicle major historical and cultural aspects of Portuguese and Spanish history.
