Seaham in County Durham, England is a compact coastal town on the North Sea with a small harbour, cliffs and pebble beaches that form part of the nearby Durham Heritage Coast. Its seafront, promenades and rock‑pools are popular with walkers, anglers and birdwatchers, and the harbour area gives the town a distinctive maritime feel even though industry has changed over the years.

The town expanded in the 19th century as a coal‑exporting port built by the Londonderry family and later bore the social and economic shifts of the mining era. In recent decades Seaham has seen regeneration - historic buildings such as Seaham Hall have been restored, and there’s a modest mix of cafes, galleries and community events; it also benefits from good road and rail links to Durham and Sunderland, making it an accessible coastal stop in the north‑east.
