Q: Question: How long is the river that Jordanne flows into? Passage 1:Carrigaphooca Castle is a ruined five storey rectangular tower house situated on a steep-sided rock overlooking the River Sullane. It is located 6 km west of Macroom, in an area once known as Gleann na n-Dearg (Valley of the Reds). The tower dominates the landscape of Lissacresig (Fairyland) in Clondrohid, and Lower Shanballyshane, in Kilnamartyra. Carrigaphooca is made of sandstone and limestone and was built as a defensive tower by MacCarthy clan member Donal MacCarthy of Drishane c. 1336-51. Cormac Teige McCarthy, the Lord of Blarney took refuge in the tower after he had sided with the Irish during the Siege of Kinsale in 1601. He stayed there until he was forgiven by Elizabeth I after he had written a personal letter of apology to her. In 1602, the castle was attacked and taken by Donal Cam O'Sullivan Beare and another member of the extended McCarthy family. After a protracted siege, their forces broke through the outer wall and burned the timber door at the north face entrance. The defenders surrendered and were allowed to go free.
 Passage 2:Aurillac is at above sea level and located at the foot of the Cantal mountains in a small Sedimentary basin. The city is built on the banks of the Jordanne, a tributary of the Cère. It is south of Paris and north of Toulouse. Aurillac was part of a former Auvergne province called Haute-Auvergne and is only away from the heart of the Auvergne Volcano Park. Access to the commune is by numerous roads including the D922 from Naucelles in the north, the D17 from Saint-Simon in the north-east, Route nationale N122 from Polminhac in the east which continues to Sansac-de-Marmiesse in the south-west, the D920 to Arpajon-sur-Cère in the south-east, and the D18 to Ytrac in the west. The Figeac-Arvant railway passes through the commune with a station in the centre of town but there is no TGV service. About 50% of the commune is urbanised with farmland to the east and west of the urban area.
 Passage 3:Bahlul Ibn Marzuq (died 802) was born in the current term of La Puebla de Castro (Huesca), was a Vascon-Muslim, the son of a local lord named Marzuq ibn Uskara ("son of the Basque"). He rebelled in Zaragoza against the Arab-Muslim government of Al-Andalus in 798, and in 800 conquered Huesca from the Banu Salama. His rebellion carried popular support, especially after public backing by theologian Ibn al-Mughallis. The emir sent the Huesca native, general Amrus ibn Yusuf, and Zaragoza and Huesca were retaken (c. 801). Bahlul fled to Pallars where he was killed by his lieutenant Jalaf Ibn Rashid (802), who at the time held Barbitanya (Barbastro). The adventures of Bhalul were collected by the Muslim historian and geographer Ahmad ibn Umar al-Udri (1003-1085) in the popular epic poem written in Arabic known as "the archuza de Bahlul".
