El Cronicón de Oña Activity · Oña, La Bureba, Burgos Image of Oña, not of the place itself. Every August, from the 11th to the 15th, the people of Oña perform through the streets and inside the church of the Monastery of San Salvador a play that dramatises a large part of the town's medieval past, with hundreds of extras and period costumes; the last two years it has been staged in the Patio de San Íñigo of the monastery itself. The performance recreates the origins of the monastery, founded in 1011 by Count Sancho García and his wife doña Urraca, who named their daughter Tigridia its first abbess, within the account of the struggles of the Castilian counts, from Fernán González to Sancho García, against Almanzor. It is the people of Oña themselves who perform it, with no professional interest, passing the tradition on to new generations. Photo: WikiBurgos (CC BY 3.0) What to see and do in Oña
