3 of 8 The 'Closing the Door?' exhibition looks at the experiences of eastern European Jews targeted by the Aliens Act and those of other immigrant communities in Britain over the past 100 years.
4 of 8 The contribution made by generations of immigrants to the UK's economy and society is highlighted.
