34 Montagu Square is the address of a London ground floor and basement flat once leased by Beatles member Ringo Starr during the mid-1960s.

Many well-known people have lived at the address, including a British Member of Parliament, Richard-Hanbury Gurney, and the daughter of the Marquess of Sligo, Lady Emily Charlotte Browne.

For three months, John Lennon and Yoko Ono rented the flat, taking a photograph that would become the cover of their Two Virgins album.

After the police raided the flat looking for drugs, the landlord of the property sought an injunction against Starr to prevent it from being used for anything untoward or illegal.

[2] It was named after the Yorkshire-born Elizabeth Montagu:[3] a social reformer, patron of the arts, salonist, literary critic, and writer.

The square is an example of Regency terrace residential architecture that was popular in the 19th century, with a communal garden located in the centre; surrounded by iron railings and padlocked so its use would be limited to residents.

On 24 July 1965, Starr bought Sunny Heights for £30,000 ($72,000),[18] on South Road, St George's Hill,[19] but retained the lease on the flat.

[27] Sommerville recorded Burroughs there,[15] for Apple's Zapple label offshoot, but discouraged other people who were interested, believing he was working for McCartney exclusively.

[28] During the time Sommerville was recording Burroughs, a friend of McCartney, Barry Miles, visited the apartment: Ian [Sommerville] was in the strange position of playing host in Ringo's expensive apartment, fixing everyone drinks, fussing about, cautioning everyone not to lean against the green watermarked silk wallpaper in the sitting room.

[29] McCartney later gave up the flat, and it remained empty until Starr sub-let it to Hendrix with Kathy Etchingham, and Chandler with Lotta Null, in December 1966,[30] for £30 ($63) a month (£265.12—$591.62 today).

[33] For three months, between 1966 and 1967, Hendrix shared the apartment with Gordon Haskell, a bassist who played with the psychedelic band Les Fleur de Lys.

[35] Starr also lent the flat to other pop stars and friends over the next few years, when they needed a place to stay in London.

Visitors remembered that the flat was in a state of squalor, with dirty plates, cups, clothes, newspapers and magazines littering the floor,[39] with the couple living on "a diet of champagne, caviar, and heroin".

[40] Lennon and Ono's experimental Two Virgins album had been recorded at Kenwood, but its notorious nude cover photos were taken at 34 Montagu Square.

[44] In 1974, Lennon remembered that Ono answered the front door as a female voice had said (over the intercom), that there was a message from the Apple office.

[52] A music label owner, Reynold D’Silva, bought the flat for £550,000 in 2002, beating a rival bid from Noel Gallagher.

[26] Author Miles contended that 34 Montagu Square "clearly qualifies as a candidate for one of the blue marker plaques that the City of Westminster fixes to buildings of historical interest".

[28] On Saturday 23 October 2010, following a 10-year campaign by proposer, Peter Davies, and in front of 100 people, Yoko Ono unveiled a Blue Plaque at 34 Montagu Square: "John Lennon, 1940–1980, Musician and songwriter, lived here in 1968".
