Located on the Forth coast, between Cockenzie and Longniddry, Port Seton forms the larger part of the combined burgh of Cockenzie and Port Seton in East Lothian. The original houses, of which few remain, overlook the harbour. Port Seton House is C-listed and dates from the early 19th C., on the site of an earlier house. Along the shore are fine terraces, with crowstepped gables, built by the Wemyss Estate in 1882. Victorian and Edwardian development gives way to 1930s bungalows to the east. Public housing was developed to the south beginning before the Second World War but continued in the 1950s and 60s. Substantial number of private housing was developed to the south thereafter, into the 21st century.
Port Seton is now a dormitory village and holiday resort, but was traditionally known for fishing and salt making village with the latter declining by the mid-19th Century. Seton House and Seton Collegiate Church lie to the southeast while, to the east are Seton Sands, a favourite holiday spot with an extensive leisure village including lodges and residential caravans.
