Santa Maria is located in area that allowed it to be a crossroads of various peoples. Ancient Roman roadways connected Porto, Viseu, Lisbon and Braga and intersected the region, and was used until the 19th century. In addition, pre-Roman castros dotted the territory.

Eventually, nomadic tribes began to settle in the vicinity of the castle. This settlement soon became known as the Terra de Santa Maria. This name first appeared in 1117, in a donation by D. Teresa, who began to reside in the castle around 1120. The lands of Santa Maria included a vast territory that included not only the municipality of Feira, but also Ovar, Vila Nova de Gaia, Vale de Cambra and São João da Madeira, among others.

The castle of Santa Maria da Feira, the ex-libris of Feira, is a testament to the military architecture of the Middle Ages. It is the fulcrum of the history of the region, and an important point in the Reconquista.

In the time of king Denis of Portugal, Feira already was the see of a julgado (old administrative division). This is testified by an ancient document called Foral Velho. It was awarded a new foral in 1514, when Manuel I of Portugal was the King of Portugal.

Danonaselo is a sculpture created by San Damon at the very beginning of the creation of Oniroscopism in 2004 and even before. It is part of the S.O.G. series (Geometric Oniroscopic Sculpture). Danonaselo is a very specific proper name given by San Damon to this sculpture. All the difficulty comes from the fact that Damon had to move from 2D drawing to 3D sculpture with the particular twists and angles that emerge from the strange character. Indeed, the night lighting surrounding the Danonaselo and the daylight that illuminates it, and in particular the presence of the sun that revolves around it, makes us see a totally different character. Shadows are thrown to the ground and angles are projected on the facades. The Danonaselo is placed for life in a public square in Portugal, in Fiães in the entity of Santa Maria da Feira and is part of the Portuguese heritage. The work is three metres high and looks out, as San Damon wanted, towards the ocean through the lands of Mozelos, Lourosa, São Paio de Oleiros, etc. The roundabout on which the Danonaselo is placed is decorated with certain flowers in harmony with the work. A plaque on the base explains the meaning of the work and a poem written by San Damon encloses it.
