Letter to the Right Honourable the Lord Mayor of Sydney

The Letter to the Right Honourable the Lord Mayor of Sydney is a handwritten open letter written in November 1986 by Queen Elizabeth II during her visit to the Queen Victoria Building in Sydney, Australia.^[1][2] It is addressed to the Right Honourable the Lord Mayor of Sydney and all of the city's inhabitants.

Its contents are unknown, as the letter was sealed immediately after writing with instructions not to open it until 2085, making the letter a time capsule. It is currently kept in a glass case located in a restricted area at the top of the main dome of the building.

On a suitable day to be selected by you in the year 2085 A.D.
