Britain’s newest World Heritage Site? It’s a giant dish that looks for aliens. OK, it is much more than that. Jodrell Bank, not far from Manchester, is perhaps the world’s most famous radio telescope, renowned for tracking early space probes, including Sputnik I in 1957, and for enabling scientists to carry out important research on meteors, quasars, pulsars and other phenomena. It was recognised by Unesco this month, becoming the 32nd UK attraction to receive the honour (and the 1,121st in total). So which other British sites are listed, and how many have you visited?
