 Although, the idea of a neighbourhood equal to a district was aimed, sometimes it was not possible, given the fact that some are excessively small.While most of the districts have been in common use by locals for generations, some designated names are rarely heard outside of the Planning Commission usage, such as "Parque da Cidade" or "Agro-Velho".Some districts are formed by more than one quarter, such as the Matriz/Mariadeira formed by Matriz, Mariadeira, Regufe, Penalves, and Coelheiro or the Barreiros/Moninhas District formed by Barreiros and Moninhas.
