The Church of Saint Peter of Abragão’s transept is still from the Romanesque period, a significant testimony of the Romanesque architecture of the Sousa Valley.
Outside, the frieze composed of geometric motives revives church decoration in the Visigoth and Mozarab periods, whose reminiscence in works from the 13th century constitutes one of the most interesting phenomena of the Portuguese Romanesque architecture.
The existence of the Church of Abragão is documented in 1105. However, the transept, traditionally attributed to the initiative of D. Mafalda, daughter of king D. Sancho I, is from the second quarter of the 13th century.
The rosette features the usual themes of the flaming swastika, the six petaled rosettes and the beveled palms. Inside, the capitals are a fine testimony of Romanesque sculpting.
