Brazilian colonial architecture refers to the architectural style that developed in Brazil during the colonial period, primarily from the 16th to the 19th centuries. This style is characterized by a blend of European influences, particularly Portuguese and Spanish, combined with local materials and indigenous techniques. Common features include ornate facades, large windows, and decorative tiles known as azulejos. The architecture often reflects the social and economic conditions of the time, with grand churches and public buildings symbolizing the power of the Catholic Church and colonial authorities. Notable examples include the historic cities of Salvador and Ouro Preto, which showcase the rich cultural heritage of Brazil's colonial past.
