This autumn, a few weeks into the new term, a school will close in North East London, bringing an end to 30 years of remarkable achievement.
It never appears in league tables and doesn't appear on a map, but the fictional comprehensive of Grange Hill has made an important contribution to children's TV, the perception of school life and TV drama in general.
It was the first ever soap for children and developed a controversial style in dealing with real issues - a style which became common in adult soap operas.
But in September the series comes to an end.
Comedian Robin Ince - who grew up watching Grange Hill - looks at the life and times of the series, it controversial storylines, the effect on real life classrooms and its impact on TV drama.
