Magna Britannia;: Derbyshire (1817)
Northwest of Derby, Kedleston Hall sits in all its stately glory (Kedleston Hall | National Trust) But in the Regency era, it was a relatively new home built in the mid 18th century.
A three storied home, both the exterior and interior were designed with neoclassical features including Corinthian columns and portico. The grounds include several follies and a Fishing Pavillion that includes a plunge pool (bottom right of the painting).
