Botolph Wharf is among wharves or keys east (downstream) of London Bridge
Then is there a fair Wharf or Key, called Botolph's Gate, by that Name so called in the Times of William the Conqueror, and of Edward the Confessor, as I have shewed already in the Description of the Gates.
Butolph Wharf was in the Crown in Edward the First's time, who granted it to Richard de Kingston in these Words: "Our common Key of St. Butolph next Billingsgate, London, with free going in and out to the same, in the East Head of the same Place. Which place hath Land contained from the Tenement of the said Richard against the West, and to the Head of the said Church, and the common way which leadeth to the Thames against the West, eighteen Ells and one quarter of an Ell, of the Iron Ell of our Sovereign Lord the King of England, without Inches measured. And it containeth in both Heads, from the Wall of the said Church unto our common Key in breadth six Ells of the Ell aforesaid, without Inches measured. To have and to hold to the said Richard and his Heirs, and to whom he will give, sell, bequeath, assign, or any other mannerwise Alien, and their Heirs, of us, our Successors &c. freely, quietly, well and in peace, &c. yielding therefore a Silver Penny at the Feast of the Nativity of S. John Baptist, for all Services, &c.]" -- An electronic edition of John Strype's
