Norwich castle is a medieval castle in Norfolk, England. It’s over 900 years old and a famous queen, Queen Boudica, lived there a long time ago. Today, it’s a museum and an art gallery. Here you can
see collections of art and natural history. In the Anglo-Saxon and Viking Gallery you can find out about how people lived in Norfolk after the Romans went away. There are beautiful watercolour landscapes in the Landscape and Nature Gallery. There are many more things to do at Norwich Castle.
Dungeon tours take you to secret parts of the castle. You can hear amazing stories, but children must go with an adult. You need to pay extra for this tour – £2.40 for adults and £1.80 for younger people (5–16 years old). For younger children (aged 2–4) there’s a new activity called ‘Snapdragons’. Once a month, children can discover all about different museum objects. This costs £2.50 for each child.
Get more information about Norwich Castle and its activities on their website.
