St Nicks is the green heart of York

A centre for nature and green living, with an ambitious vision for York. The charity started as ‘Friends of St Nicholas Fields’ in the 1990s by transforming a former landfill site into a thriving Local Nature Reserve. We continue to manage it, with the help of many great volunteers, for the benefit of both wildlife and our visitors. The name of the site and the secular charity comes from the middle ages when the area was owned and managed by St Nicholas hospital and church.

We are based at St Nicks Environment Centre which combines many green features. From this base, we run projects, events and services which help to make York more sustainable. The Centre is available for hire for meetings, seminars and other events. We hope you will visit us soon.
