The fen or moor (in this neighbourhood), from whence the name Moorfields, reached from London-wall to Hoxton; the southern part of it, denominated Windmill Hill, began to be raised by above one-thousand cart-loads of human bones, brought from St. Paul's charnel-house in 1549, which being soon after covered with street dirt from the city, the ground became so elevated, that three windmills were erected on it; and the ground on the south side being also much raised, it obtained the name of The Upper Moorfield.
