IntegrityThe urban framework of Brasilia includes all of the elements required to demonstrate outstanding universal value. In 1990, the Urban Framework of Brasilia was officially recognized as a national historical heritage site. The challenge of preserving Brasilia requires assessing present-day issues and demands relating to the city based on its singular urban plan. Protection of the Urban Framework of Brasilia is governed by a series of legal instruments intended to ensure its preservation on three operational levels: local, federal, and global. To address these challenges and recognizing that the preservation and protection of the Urban Framework of Brasilia cannot be disassociated from the city’s urban development, an Urban Framework Preservation Plan for Brasilia (Plano de Preservação do Conjunto Urbanístico de Brasília – PPCUB) will be the primary instrument for planning, preserving, and managing the protected area and for coordinating the measures and agents involved in Brasilia’s urban development.
