It is the widest staircase in Europe, as well as one of Italy's leading attractions.
But the Spanish Steps now has a rather more unusual claim to fame – it is, apparently, the site where actress Susan Sarandon conceived her daughter.
The Thelma and Louise star shocked an audience in New York with the intimate details, telling them she had had trouble conceiving – until she visited the 300-year-old steps in 1984 with her then boyfriend, Franco Amurri.
'If anyone out there's having trouble getting pregnant, go to Italy,' she said. 'Have a summer and don't worry about it and eat and drink and ... ****, and you'll probably get pregnant. And that's what happened with Eva on the Spanish Steps.'
Miss Sarandon's daughter, Eva Amurri, now 26, is a model and actress.
Miss Sarandon, 65, was with film director Mr Amurri for more than a year after the end of her relationship with director Louis Malle.
The actress also revealed that as a young woman she had been diagnosed with severe endometriosis, a common cause of infertility.
When actor Alan Cumming questioned what she said, Sarandon replied: 'On the Spanish steps? That's where Eva was conceived, on the Spanish steps?'
The Spanish Steps in Rome is the widest staircase in Europe and more than 300 years old and one of Rome's leading attractions.
Three years after her daughter was born actor Tim Robbins became her long term partner until they split in 2009.
Sarandon spoke about her pregnancy during a conversation with The Good Wife star Alan Cumming.
