This Neptune Statue in Dyrham Park used to be at the head of a cascade which fed a Dutch-style water garden. The house built for William Blathwayt at the beginning of the 18th century. The house and parkland are now in the care of the National Trust.
The picture labelled "Old Lodge" is not on a road like a lodge would be, and I believe they are cow sheds and farm buildings. In fact there are remains of cow stalls inside.
