In the 1960s, Danúbio Nunes, a Portuguese citizen living in Namaacha, publicised the slogan Faça da Namaacha a Sintra de Moçambique ("Make Namaacha Mozambique's Sintra"), due to some local features, namely the climate, the altitude and the proximity to the capital city, that could make it comparable to the picturesque and historical town of Sintra, in the proximity of Portugal's capital city.

This might be at the origin of Namaacha having later been twinned with:

• Sintra, Portugal

• Azagaia (1984–2023), rapper
