Caminho Niemeyer, Cultural center in Niteroi, Brazil

Caminho Niemeyer is a set of cultural buildings by Oscar Niemeyer running 11 km along Niterói's Guanabara Bay waterfront, from the 72,000 m² Praia Grande landfill in the Centre to Charitas. Its best-known piece is the Contemporary Art Museum, opened in 1996; the Popular Square in the Centre holds the Popular Theatre, the Roberto Silveira Memorial and the snail-shaped Oscar Niemeyer Foundation headquarters.

Construction of this architectural complex began in January 2002, following initiatives from the 1990s to transform Niteroi's waterfront district. The project emerged from efforts to redefine the city through significant architectural works.

The complex's name comes from the popular association of the whole waterfront ensemble with its architect, Oscar Niemeyer. The Roberto Silveira Memorial holds over 200,000 digitized titles on Niterói, Rio de Janeiro state and the former governor's life, and since 2013 has housed the Centro de Memória da História e da Literatura Fluminense. The Popular Theater's panels show three allegorical drawings of women.

The route runs 11 km along Guanabara Bay from the 72,000 m² Aterro da Praia Grande site in the Centre to Charitas, so plan which stretch to walk. Most cultural centres are closed or only partly working; the 8 tourist information posts (CAT) run by Niterói Empresa de Lazer e Turismo can advise on what is open.

The complex is still unfinished: of its projects, nine were completed, one is under construction, two are sculptures and seven were never built. Most cultural centres along the route are closed or only partly working, and by 2011 the projected cost had exceeded the initial estimate by 85%, reaching R$55 million against R$65 million.
