In a statement, Póvoa de Lanhoso City Council explains that the certification results from a cooperation and commitment protocol between the two municipalities, which also aims for the joint promotion, "in an increasingly near future, of a filigree application for World Heritage status."

"Filigrana de Portugal, a trademark registered with the National Institute of Industrial Property and owned by both municipalities, opens the door to the long-cherished dream of taking filigree beyond borders as a specific, registered, and regulated technique," the statement adds.

The certification specification book establishes the standards and procedures that this art must comply with to be designated as Filigrana de Portugal.

"It will allow a more accurate and safe use of filigree in the most varied pieces, from jewelry to clothing, decoration, and the most diverse and original articles," the same statement also notes.

Filigree is a centuries-old art that requires artisans to carry out meticulous work with small twisted gold and silver wires, which are then applied to structures of various shapes, resulting in jewelry pieces with delicate lacework.
