Sancha Ramírez (born c. 1045, died 1097)[1] was an Aragonese princess, the daughter of King Ramiro I and Queen Ermesinda.
As a twenty-year-old widow, Sancha remained for a while in Urgell, appearing in acts beside her stepson Count Ermengol IV.
Her other sister, Theresa, later also entered the monastery, probably on her brother Sancho's orders because no suitable husband could be found for her.
The elder Sancha had received the estate at Aibar with the monastery from Queen Jimena Fernández, the grandmother of Ramiro.
In 1079, she made a similar exchange of properties with San Juan de la Peña, this time accompanied by the abbess of Santa Cruz, Mindonia.
[9] In her administration of both the abbey of Santa Cruz and the diocese of Pamplona, Sancha worked to further the Gregorian reforms.
[2] Sancha was present on 4 December 1094 when the church of San Juan de la Peña was consecrated and the body of her brother Sancho was interred.
