Question: Where was the place of burial of Harald Iii Of Denmark's wife?

Knowledge 1: Harald III of Denmark
Harald III (Harald the Whetstone, ; – April 17, 1080) was King of Denmark from 1076 to 1080.Harald III was an illegitimate son of Danish king Sweyn II Estridsson, and contested the crown with some of his brothers.He was a peaceful ruler who initiated a number of reforms.Harald was married to his cousin Margareta Hasbjörnsdatter, but did not leave any heirs, and was succeeded by his brother Canute IV the Saint.Four of his half-brothers were in turn crowned Danish kings, with his youngest brother becoming the Danish king known as Harald IV (Harald the Young), Danish: Harald Olpe. [SEP] Knowledge 2: Margareta Hasbjörnsdatter
Margareta Hasbjörnsdatter or "Margareta Asbjørnsdatter" (11th century) was Queen consort of Denmark as the spouse of King Harald III.Margareta was the daughter of jarl Asbjörn Ulfsen, possibly an uncle of her spouse; she would thereby have been her husband's cousin.No children are known from the marriage.The dates of her birth and death are unknown.A DNA test in 2003 dispelled the centuries-old legend that Estrid Svendsdatter was buried in the northeastern pier of the Roskilde Cathedral.The new theory is that the sign on the pier refers to Margareta Hasbjörnsdatter, who was also known as Estrid.

[SEP] Knowledge 2: Olaf (II) Haraldsen
Olaf Haraldsen( died) was a Danish anti-king who ruled Scania for a few years from 1139.He never won control over the rest of Denmark, and he is not included in the list of Danish monarchs used by the Danish monarchy or" Den Store Danske Encyklopædi".He is sometimes called" Olaf II" even though there was a later Olaf II of Denmark.He was the son of Harald Kesja and thus nephew of King Eric II of Denmark.He seems to have been the only who escaped Eric II's murder of Harald and his sons in 1135.After trying in vain to regain his heritage, Olaf proclaimed himself king in Scania in 1139, fighting his cousin King Eric III of Denmark.The civil war mostly consisted of alternating raids, during which Olaf killed Bishop Rike of Roskilde, an act that saw him excommunicated by the Pope.He was at last defeated by Eric III and was killed in a battle in Middle Scania around 1143.Harald Skrænk, the leader of a peasant rebellion in Scania about 1182, is said to have been Olaf's illegitimate son, but their connection is unsure.
