yup the morningrise bridge is in prior park, bath. there are several palladian bridges, all of them are copies.
There is another one in stowe gardens, buckinghamshire, and that one in wiltshire but the one in the cover is in bath (near a place called fox hill... coincidence?)
as far as i know the one in wilton park was the first one to be built in england, in 1738, by the Earl of Pembrokshire and his architect Roger Morris.
The original design was by Andrea Palladio (hence the name), for the Rialto Brdige in Venice, but was never built there.
