This section runs along the edge of the Dingle and Westwood Marshes, and through the village of Walberswick, before crossing the River Blyth, and entering the town of Southwold. Walberswick became a major trading port from the 13th Century. The British Open Crabbing Championships are held every August, with the winner being the person who catches the heaviest crab within 90 minutes. Almost half the properties in the village are holiday homes. Southwold was an important fishing port in the Domesday book. It was badly damaged in a fire in 1659, and many of the buildings were not rebuilt, leaving open spaces or greens that remain to this day. The town contains a popular pier, has a lighthouse in the centre, and is home to Adnams Brewery.
