To keep the site it needs to be occupied all the time, so visitors are always welcome. There's food and tea and plenty to do. The site has only been under occupation for a few days so it's an exciting time and people with ideas and enthusiasm are needed to come and contribute. At the moment it's all of our space - let's keep it that way.
The boatyard is a vital resource for people who live in boats. British Waterways, the body that is supposed to maintain the UK's canals, is selling off bits of land around the country - Jericho is not the only boatyard that is under threat. British Waterways plans to sell the site to Bellway Homes, which is seeking planning permission (not yet granted) to build luxury flats. There is a need for sustainable and affordable living space in Oxford but this would not be provided by the Bellway development.
The Jericho boatyard is also famous for having inspired Philip Pullman's 'His Dark Materials' trilogy. A lot of history and culture would be lost by building over it, making Jericho and Oxford a culturally poorer place.
