Hi – Great thread – I was hoping that one of viewers maight throw some light on a question that has been tasking a few like minds in Galway. With regard to the keystone on the top of a 16th, 17th century castle, tower house or church doorway – why is the right side of the keystone longer than the left. It is always the right side which is longer as you walk in.

If anyone could assist us in this – it would be appreciated.

Thanks
