Chapels in beaches and hills Important locations for the study of siglas poveiras include churches and religious sites not only in the city and its rural surroundings but also across the entire Northwest Iberian Peninsula, particularly in the Minho region of Portugal and in
Galicia. Over generations, the Poveiros used to inscribe marks on the doors of chapels near beaches or hills, either as journey markers or as "campaign promises" (
promessas de campanha). This practice has been observed at Nossa Senhora da Bonança, at Esposende Beach and at Santa Trega on A Guarda Hill in Galicia. The inscription would serve as a marker for future Poveiros, indicating either the passage of the inscriber or an attempt to seek good luck from the local venerated saint. On 23 September 1991, a sculpture honoring the siglas poveiras was inaugurated at the festival of Santa Trega in Northwestern Spain, commemorating the lost door of the Chapel of Santa Trega, which is known to have been covered with siglas poveiras. Following the inauguration, a fishing expedition aboard the
Lancha Poveira Fé em Deus (Faith in God) arrived from Póvoa de Varzim. The fishermen aboard then ascended to Santa Trega and prayed at the chapel dedicated to the patron saint of the hill. Hills near the coast, visible from the sea, have always held significance in Poveiros traditions. Long ago, members of the fishing community would climb this hill to pray to the saint, performing a ritual with chants aimed at changing the direction of the winds to ensure a safe return home. Siglas used in much the same way can be found in the churches of Senhora da Abadia and São Bento da Porta Aberta in
Terras de Bouro, São Torcato in
Guimarães, Senhora da Guia, and
Vila do Conde. In the municipality of Póvoa de Varzim, they can also be found in the Chapel of Santa Cruz de Balasar.
Divisas The fish caught in a boat's net belonged to its owner, regardless of their position within the Lanchão or Sardinheiro castes. The fish were marked with the
sigla and then delivered to the owner of the fishing net. These fish marks typically consist of blows made in the form of a
sigla in different parts of the fish. The crew of each boat also had a
sigla, which was used by all members of the crew. If a worker moved to another boat, he would have to adopt the
sigla of the new boat. These boat marks were known as
divisas. The
divisas are true "coat of arms" intended for the recognition of the boat. However, they were different from the boat owner's mark. All Poveiro belongings were marked with the owner's personal
sigla, except for the boat. This suggests that boats were predominantly subject to magical-religious invocations, often adopting a protecting saint, thereby acquiring a mythical character and being surrounded by protective symbols.
Marriage marks The Poveiros wrote their
sigla on the table of the mother church upon marriage as a way of recording the event. This use of
siglas can still be found in the Igreja Matriz of Póvoa de Varzim (the mother church since 1757) and in the
Igreja da Lapa. A table in the old Church of Misericórdia, which served as the mother church until 1757, contained thousands of
siglas. The collection of these
siglas would have greatly contributed to a deeper study of the siglas poveiras, but they were destroyed when the church was demolished. ==Origins==
