If you are in Gloucestershire, why not visit Berkeley Castle.
In 1153 Lord Maurice Berkeley completed this fortress by the Severn Estuary at the command of Henry II, and ever since it has been the ancestral home of the Berkeley family, one of England's oldest families who have given their name to numerous locations all over the world, from Berkeley Square in London, to Berkeley Hundreds in Virginia, and Berkeley University in California.
There is also a Butterfly Farm set in the walled garden adjacent to the car park.
I last visited this castle in 1992, so am unable to give you current admission prices.
The picture is taken from the leaflet we were given, sorry about the poor quality.
Berkeley Castl;e is situated by the town of Berkeley just off the A 38 midway between Bristol and Gloucester. From the M5 motorway exit at junction 14 or 13.
