I've just spent a week in the Cotswolds. It is full of quaint picture postcard villages and I guess many overseas visitors have this area as their perception of England.
So I guess Sezincote comes as something of a surprise. It is was built in the Indian Style a combination of Hindu and Muslim architecture. The Prince Regent visited in 1807 and the house is said to have influenced the Brighton Pavillion.
It is visited by guided tour and it is well worth a visit. The gardens are lovely as well.
