Chavenage House, a Grade I listed Elizabethan manor built in 1576, represents the ideal 16th-century Cotswold stone manor house with its E-shaped layout and mullioned windows. Built by Edward Stephens and remaining in the family for over 450 years, the house retains authentic period features including tapestries, furniture, and Civil War relics from its time as a Parliamentarian stronghold. The unaltered Elizabethan architecture with original oak paneling, stone fireplaces, and period portraits creates an immersive historical experience. Its authentic atmosphere and minimal modernization have made it a favorite for period productions, most notably as Trenwith in Poldark. **Filming Scenes:** Chavenage provided various interior scenes throughout Downton Abbey, utilizing its authentic Elizabethan rooms to represent different aristocratic houses visited by the Crawley family. The great hall, with its minstrels' gallery and Tudor furnishings, appeared in formal dinner scenes, while the oak-paneled bedrooms served for intimate character moments. The house's genuine period atmosphere, without modern intrusions, meant minimal set dressing was required. The combination of different architectural periods within the house - Elizabethan, Jacobean, and later additions - provided varied settings for different narrative requirements.
