The Memorial of Santo António, also known as Arco da rainha Santa, is a romanesque monument from the 12th century, considered one of the most significant of its kind in the north of Portugal, and there are only six copies, of this style left in the country. According to the legend the memorials of Santo António, in Arouca, of Ermida, in Penafiel, of Sobrado, in Castelo de Paiva, of Alpendorada, in Marco de Canaveses, and of Lordelo (now extinct, in Baião), are referred to as stopping points of the shuttle carrying the body of Queen Mafalda, daughter of King Sancho I and granddaughter of King Afonso Henriques, from rio Tinto to the Monastery of Arouca, or as tribute places to her life and work. The Santo António Memorial, considered of high historical and architectural interest, was classified as a National Monument by a 1910 decree.
