In addition to the Norfolk Community Directory www.norfolk.gov.uk/directory here is another information resource which can help you find out what is happening locally in a specific area:
The Bright Map project aims to highlight some of the amazing community engagement and support across Norfolk.
It was initially founded by the Church of England Diocese of Norwich to promote groups and activities churches run for the benefit of their local communities. Today the site is open to all and promotes projects and community activities run by a wide range of organisations and community groups. If you know of a locally run group in your local area, or perhaps you coordinate your organisation’s groups across the County for the benefit of the community, the Bright Map project would love to hear from you.
You can find a link to the Project here: https://www.brightmap.org/
