[2] The 1086 Domesday Book gives Ilecliue also variants Illecliue, Illiclei and Illicleia for Ilkley.

Modern scholarship has, however, suggested that the Roman name would be better applied to the fort at Elslack (Eleslac in Domesday Book) near Skipton.

[1] A second fort was erected around 161 AD which survived for 30 years, before being burnt down,[3] perhaps during a documented rebellion by the inhabitants of northern Britain.

[6] The area of the fort extends underneath the Manor House and nearby All Saints Parish Church whilst the vicus probably existed from the car park in the centre of Ilkley to Christchurch on The Grove.

[7] The Roman altars date to the reigns of Antoninus Pius (138 to 161), and Septimius Severus and his son Caracalla (211 to 217).
