In the middle of a poor nineteenth century area in Rotterdam stands a beautiful pan optical gaol built in the 1880's. It is a star in a square. It is an landmark of the utmost historical importance. It also functions very well as a prison. Since the seventies social democrat city government has promised the neighbours that it will be demolished and replaced by a park. City Government has nothing to say about it however, only the ministry of justice and the heritage department. The jail will only leave in another decade; we propose slowly fading the gaol out of the neighbourhood, gradually acquainting the inhabitants with the possibility of reusing gaol building and its large grounds as a public, active and open park like complex. Hybrid forms between gaol and city are assembled: a park guarded by prisoners in their last phase of incarceration; double use of the sports facilities of the gaol; using the security system to also guard the public space and the shops of the neighbourhood. Just like the prisoners, also the gaol building will be gradually resocialised.
