Mastro Sol
Mastro Sol is a participatory work that weaves together installation, culinary-atelier, and public celebration through the collective creation of edible biscuit-dough flags. Developed in community workshops, the flags are suspended within a ceremonial structure and later shared during the final activation gathering as an act of encounter and collective celebration.
All dates

Mastro Sol
In this workshop, each participant shapes and creates their own edible form (biscuit-flag) made from biscuit dough that will be suspended as part of Mastro Sol, an installation inspired by vernacular celebrations and the mastros de promessa of the Alentejo region, where circular cakes are traditionally suspended on festive structures. Each form preserves the gesture and intention of the person who made it, becoming part of a collective artwork shaped by many hands. On June 27 at 11:30 am, when Mastro Sol is activated by the public, participants are invited to rediscover their own flag, see how it became part of the final installation, and harvest it to share, offer, or eat.
Within the context of the Art Explora Festival presented at Cascais Marina, the work establishes a relationship with the way the festival itself arrives in the city: coming from the sea, settling alongside the harbour, and creating a temporary presence in the public realm. Mastro Sol extends this movement onto land, transforming the marina area into a meeting point for visitors, participants, and local residents.
The mastro works simultaneously as a landmark and a call to gather. Through its verticality, it marks a point in space and creates a shared reference. Around it unfolds a collective action that brings the artistic installation closer to vernacular cultures of celebration, where the knowledge of the hands is an essential part of the shared experience.
The image of the sun is the central reference of the work—not only as a visual form, but as an idea associated with cycles, celebration, and collective vital energy. The sun is understood as a unifying presence: that which brings people together, marks rhythms, and accompanies communal practices linked to festivity, food, and encounter.
The process begins in workshops, where participants create edible biscuit flags from dough. The act of kneading and shaping the dough transforms an everyday material into a sculptural element, bringing culinary practice closer to artistic practice. Each flag retains the unique imprint of its maker. Once baked, the pieces are suspended from the mastro structure.
The activation of the work takes place in collaboration with the group Zarabatana, whose sonic presence expands the moment in which the biscuit flags can be harvested and shared. This transitory dimension is fundamental to the artwork: what has been collectively built is transformed through the act of eating what has been collectively made.
By bringing people together around a shared action, Mastro Sol proposes an experience situated between installation, collective creation, and celebration.
