The striking home was built on the Attingham estate for Francis Walford, an agent and friend to the 2nd Lord Berwick, between 1802 to 1805.

It is the first and best known example of architect John Nash’s Italianate villa designs.

Cronkhill is an asymmetrical composition of two towers, one circular and one square linked by a colonnade on the east side. The whole house is attached to a 17th century timber-framed farmhouse.

Following the tenancy of Walford, Cronkhill was predominantly occupied by members of the Berwick family, being a more modest home for them than the larger Attingham. Attingham was either shut up or tenanted during this time, until the 8th Lord and Lady Berwick returned there in the 1920s.

Cronkhill’s most notable resident was the 5th Lord Berwick, who made the name of the house famous in the rifling world, by patenting his innovative design as the ‘Cronkhill rifle’.

Engagement and Conservation Manager, Catherine Turnbull, said: “Cronkhill is a beautiful property – a real hidden gem. Don’t miss these two rare opportunities to visit the ground floor rooms and then stroll around the stables and gardens. As it is a tenanted property there are only a few chances a year to see it – so make sure you don’t miss out and plan a visit.”

Cronkhill is open on 11am to 4pm on Friday 10 and Sunday 12 June.

Entry is free for National Trust members. For non-members admission charges apply. Adults £.3.50 and children £1.80

Cronkhill is located on the road between the A458 at Cross Houses and the B4380 at Atcham.
