Translate the following English sentence to French:
"Architectural cultural heritage, land developed and cultivated by man and urban cultural heritage belong together, but the picture is not complete unless it also includes monuments to contemporary history, from the world of work for example, such as developments in working life, the building of factories, machines and so on and so forth."
Le patrimoine architectural, le paysage culturel et le patrimoine urbain vont ensemble, mais ils constituent un tout incomplet s'ils ne contiennent pas également des monuments historiques qui proviennent par exemple du monde du travail, comme l'évolution de la vie au travail, la construction des usines, des machines et ainsi de suite.
