Copyright: Production team. 1  Entomology is a branch of Zoology which deals with the study of insects. 2  The word originates from the Greek word 'entom', meaning 'notched' which relates to the segmented body of an insect. 3  These insects are by far the most numerous animals on the earth.
It was founded in the aftermath of the Norman conquest of England when William the Conqueror (1066â1087) ordered its construction because he wished to have a fortified place in the important city of Norwich. It proved to be his only castle in East Anglia. It is one of the Norwich 12 heritage sites. The castle now houses the Norwich Castle Museum & Art Gallery, which holds significant objects from the region, especially archaeological finds.
Clitheroe Castle Museum is adjacent to the castle. The castle was listed as a Scheduled Monument on 10 April 1915 (and later, under the Ancient Monuments and Archaeological Areas Act 1979 law).It was Grade I listed on 19 May 1950.t has been suggested that Clitheroe Castle may have been first built before 1086 as there is reference to the  castellatu Rogerii pictaviensis  in the Domesday Book entry for nearby Barnoldswick. However, it is likely the passage refers to another castle.
