Can anyone throw some light upon this please?

I'm involved in a very low key archaeological dig and today we unearthed these pieces of pottery, now placed together for the photographs.  What do the letters CHDDC or perhaps CHDOC above the door refer to?  The ruins we are digging  are an enigma at the moment, but on-going.  There may have been a house there but this plate is the first significant evidence of domesticity we have found as yet, although there is evidence of farming and possibly industry having taken place there.

My first thought was that it could be Delft pottery, but I'm no expert.

Diameter of the plate ??    (You can get a pretty good idea by drawing round the rim of the bit you have, and then completing the circle !)

Any markings on the back?

Blowing your second picture up even more, it looks more like CABOC .... (or possibly CABDC)

It say's "school" over the door

Doh .... you beat me to it !    Of course it does .... and that explains the children leaving in a hurry through the door !

You're right YT. So unless made for export may not be Dutch.

Looking at the top picture, I thought the word read "SCHOOL", though I do agree the letters look more like initials when viewed under magnification.

However, if they were significant initials, standing for a club or something similar, I would expect them to be larger and clearer.

ADDED - I see I'm not alone!

The plate is approx. 6.5" in diameter.
