I'm a church!
Well done! This is quite a difficult name to guess. The first part of this name comes from the Old English word cirice, which means 'church'. Old English is the language spoken by the Anglo-Saxons. Chirbury means 'church fort or manor'.
Some things to think about:
Why do you think the Anglo-Saxons named this village after the church? What materials do you think the church was made from? Do you think that every Anglo-Saxon village had a church?
