The original 'Old Town' of Edinburgh enclosed by the red line.
Tolbooth, High Church, Trinity College, Old Church, Tron, New North, St Johns,
Lady Yesters, Old Greyfriars, New Greyfriars.
Note - The boundaries of St Johns and Old and New Greyfriars vary slightly on different maps I've looked at.
The light blue line encloses the parishes of the 'New Town'
(until the new town was built, this area was part of St Cuthberts).
St Stephens, St Marys, St Georges, St Andrews.
Note - I've seen two very different versions for the new town, one has only 2 parishes. However, the blue boundary I've shown is fairly consistent. I'm not sure when/if the portion of St Cuthberts north of Register House was later incorporated into St Andrews.
