Conisbrough Castle stands above the River Don on a natural limestone and clay hill. The remains consist of an outer bailey bounded by earthworks, an inner bailey of c.1200, and a stone keep, which is the earliest and most significant building remaining on the site. Extensive damage to the gates, bridge, and walls of the castle was recorded in 1537-8; in addition one floor of the keep had by that time probably fallen in. (Renn 1973,155-7; Toy 1966, 105-7.) Conisbrough and its chapel was used by Sir Walter Scott as the setting for his novel Ivanhoe. The keep, built of fine limestone ashlar c.1180-1202 (see below, History, chapel, for the dates) is cylindrical with six trapezoidal projecting buttresses, the whole keep on a splayed base. The sides of the buttresses have alternate courses of plinth and chamfered stone. The diameter of the base is 19 m; the thickness of the walls above the splayed base 4.6 m and the highest point of the surviving keep is 28 m above ground. There is a single main room at all four levels: a vaulted storage chamber and well in the basement, a work and storage area at the entrance (first) level, the hall on the second floor, the chamber on the third floor with a chapel and sacristy lying off it, and the roof level with a wall walk. Each of the second and third floors has a window, fireplace, stone lavabo basin and latrine. The internal floors and roof were rebuilt in the mid 1990s, until then the sculpture on the fireplaces was open to the rain. The Lord’s apartment has a private chapel. This opens off the main chamber, and is contrived in the thickness of the wall and the SE buttress. The chapel is an approximate elongated hexagon, and is vaulted in two bays. A small L-shaped vestry opens off it on the N wall in the first bay. The stonework in the chapel appears to be damp in the vaulting. There is sculpture on the fireplaces on the second and third floors, and in the chapel on the third floor. The N and S walls of the chapel have circular windows in the buttress, these are quatrefoil on the outside.
Harold Godwinson (King Harold) owned the manor of Conisbrough before 1066. By 1086 it had come to the Warenne family, who built a motte and bailey castle here (Clay 1949). Architectural historians ascribe the stone castle to Hamelin Plantagenet (bastard brother of Henry II who married Isabella the Warenne heiress in 1164 and died in 1202) on the grounds that the only close analogy to the circular keep with its trapezoidal towers is Hamelin’s castle of Mortemer (Seine Maritime). The keep has been dated c.1180-1190 on the basis of the chapel decorations (Johnson 1989); but we believe for the reasons set out in the following paragraph that it must be dated c.1180-1202. The date of the chapel within the keep is of interest as the chapel serves to date the whole stone castle and the curtain wall probably followed the building of the keep after only a very short interval (Thompson 1977, 5). The chapel within Conisbrough castle, dedicated to SS Philip and James, was granted rents by Hamelin earl of Warenne and Isabella, countess of Warenne, with the assent of William their son and heir, in an undated grant only known from 17thc. copies. Hunter believed that the grant (50s in rents from the local mill) marked the chapel’s foundation. This grant was tentatively dated 1180-1189 by Clay (Clay 1949, no.74, 100). 1180 is the earliest date that the heir would be old enough to consent (his parents were married in 1164) and seems secure. The grant uses the phrases pro salute, or pro salute animae (for the safety of the soul/s) of various people, both dead and alive, one being King Henry II (d. 1189). Clay chose 1189 on the assumption that Henry was still alive when the grant was made, but that is an unsafe assumption: in which case the latest date of the chapel grant would be 1202, the death of Hamelin earl of Warenne; the date that Hunter uses (Hunter 1828, I, 107). Stylistically a date before 1180 seems unlikely. See the Comments section for the dating of the sculpture.
