Alminhas or Nichos de Alminhas do Purgatório are a type of wayside shrine typical of Póvoa de Varzim, Portugal. These small shrines are mostly urban and represent souls in Purgatory.
Alminhas are located in several streets of the city, often at crossroads. They are generally stonework, with a small niche protected by an iron grid that is kept by the Confraria das Almas (Souls Brotherhood), with an azulejo panel invoking the souls of Purgatory. Older alminhas in the city center such as Rua da Conceição-Rua Primeiro de Maio Alminha or Rua dos Ferreiros-Praça do Almada Alminha have a more elaborate niche, resembling an altarpiece.
Traditionally, passers-by would pray and offer alms when passing one in the street. Candles, flowers and alms can be place in the niche. All the city's alminhas are well preserved and kept by the brotherhood. However, due to theft and damage of the shrines, some alminhas no longer accept alms.
