:I agree that Chester Castle is a bit thin on the history section but I've added all the info I can find in my sources.  If you add more I would be delighted.  Re Crewe Hall, I think that is excellent and should easily get a GA rating.  The assessors usually come up with a few quibbles (although amazingly they did not with Chester Cathedral).  One quibble they may make is about a mixture of metric and imperial measurements (miles, hectares and acres); the best tactic would be to give all units in both imperial and metric.  As a matter of interest, was the Paris Exhibition of 1878 the same as Exposition Universelle (1878)?
