In this way a varied but harmonious townscape, with attractive detail of porches and interior panelling, grew up on a rectangular grid of new streets. Charles Street (at first called Cross Street) was laid west to east as a continuation of Greville Street, and the Bishops' orchard, which (as shown in Richard Newcourt's map of 1658) the Hattons had laid out as a walled knot garden with a central fountain, lay north of that up to Hatton Wall. Hatton Street followed the line of its central path. By 1666, the year of the Great Fire, the development had advanced north to form two principal blocks up to the line of St Cross Street (then called Little Kirby Street). The remaining open land was used as a refuge by Londoners escaping the Fire, which did not consume Hatton Garden.
