Located at the junction of Dig street and St John street, this is a high muggle area so extreme stealth is needed!
There are tall (for Ashbourne) buildings nearby so GPS may be affected, but there are some fantastic Georgian buildings nearby to admire.
There is a handy rest to write on and this can make a good spot to stop for a breather.
There is no parking in the immediate vacinity, though there are loading bays if you're quick. Dig street has on street parking before you cross the bridge, alternatively Shawcroft carpark allows 30 minutes free parking and then paid after.
