Seaham Hall is an English country house, now run as a spa hotel, in County Durham.
In 1815 the poet Lord Byron married Anne Isabella Milbanke at Seaham Hall.
Seaham Hall was one of the many properties acquired by Charles William Vane, 3rd Marquess of Londonderry through his second marriage to Lady Frances Anne Vane-Tempest in 1819.
In 1984, it was acquired by the Jalal family of Sunderland, who worked at rebuilding, renovating and returning the deteriorated building to its former glory.
In June 1997, Seaham Hall was purchased by a local businessman, Tom Maxfield, and his wife Jocelyn.
