Montagu Square is a square in the upmarket district of Marylebone in London.
In 1965 Beatles drummer Ringo Starr, leased a flat at 34 Montagu Square. When he married Maureen Cox they moved to their new home, Sunny Heights, outside of London. But Starr kept the lease and during the years to come many people would come to live there. Paul McCartney installed recording equipment planning to use the place as a studio hideaway, he also wrote several Beatles songs here including Eleanor Rigby, but eventually gave up the flat. In December 1966 Ringo would rent it to American gituarist Jimi Hendrix and his manager Chas Chandler, but evicted them after just four months after they painted all the rooms black.
Another resident was John Lennon's mother-in-law Lillian Powell, who would stay at the flat when she came to visit her daughter Cynthia Powell.
This was also the flat where John Lennon and Yoko Ono first lived together in 1968. It was the location where they photographed their nude cover for the Two Virgins album cover and also the scene of the October 1968 drugs bust that would put them both in court facing drug charges.
