Seaton Delaval, Seaton Valley - Northumberland (UA)

Remains of an early-C18 park and garden, partially restored in the 1950s-60s. The house and landscape were designed by Sir John Vanbrugh in 1719. The approach avenue is deteriorating and woodland regeneration is concealing key landscape features, including earthworks and the mausoleum. Ha-ha walls and corner bastions are being damaged by scrub and tree growth, with areas of partial collapse. A Conservation Management Plan has been produced. The site was awarded a Heritage Lottery Fund grant in 2016 and conservation works are due to begin in autumn 2018.
