Residents stop to pay their respects as the procession gets underway in Albert Square.
The legendary character - who is played by actor Leonard Fenton in the BBC soap - succumbed to his battle with cancer after finally returning home to Dot Cotton's house.
As he lay in bed, Dot put on a documentary about fascism in the UK in the 30s and 40s.
Viewers were left in floods of tears over the heartbreaking scenes.
One wrote: "#EastEnders have wrecked me with the Dr. Legg story."
A second said: "What an emotional, yet sombre and beautiful ending to tonight’s episode. R.I.P Dr Legg - a true original Walford icon and a legendary Doctor."
Another added: "What the hell #EastEnders that was soooo sad."
