Keystone uncovered

Latest find! What better way to spend boxing day.....letting myself loose on the vine and wisteria that runs along the front of the house, thinning out the dead branches and twigs that haven't been touched for years i spotted for the first time since we moved in, this keystone above the front door, so no doubt as to the date of the construction of the house now.

Not quite sure what the hole beneath the date was for but have been given some old pictures from the previous owners which may reveal if it was a lamp or something similar....i'll let you know if i find anything!!
