Sedgefield has attracted particular attention as the Member of Parliament for the wider Sedgefield constituency was the former Prime Minister Tony Blair.
During November 2003, Sedgefield was visited by the American president George W. Bush during a state visit. He visited a local pub, as well as the local secondary school (Sedgefield Community College). This event was preceded by high-intensity security, which included fastening down manhole covers and drains, and closing the centre of the village to all traffic. An anti-war protest coincided with his visit.
St Edmunds church in Sedgefield is noted for its ornate 17th century Cosin woodwork, unique to County Durham: this is especially precious now that the display in Brancepeth has perished through fire.
The 18th century saw the architect James Paine commissioned by John Burdon in 1754 to design and construct a Palladian estate at nearby Hardwick Hall. Unfortunately the building work was never completed as Burdon went bankrupt, but sufficient landscaping was done to form the basis of today's renovated Country Park. In the 19th century, Sedgefield was a great hunting centre, dubbed 'the Melton of the North'. Ralph Lambton, the celebrated hunting man, had his headquarters at Sedgefield: the humorous writer, Robert Smith Surtees, who lived at Hamsterley Hall, was a friend of his. On 23 February 1815, (while Lord Byron was moping at Seaham Hall, not far away) Lord Darlington writes: 'Mr Ralph Lambton was out with some gentlemen from Sedgefield, and a most immense field.'
Sedgefield is twinned with Hamminkeln, Germany.
