The village flourished as a port until, in 1286, a huge storm threw sand/shingle across the harbour diverting the river and destroying trade. By 1677 the sea had reached the market place and Dunwich had become an estate village.
Sizewell itself is a small fishing village and a few small boats still operate from the beach. Two nuclear power stations have been built outside the village. Sizewell A is in the process of being decommissioned and Sizewell B is still in production. There are plans to build a third on the site, to start producing electricity in 2031. Offshore there are two platforms. These are no longer in use but were there to service the intake and discharge tunnels used to run sea water through the cooling system. The cold water inlet was the farthest platform and the hot water outlet was the nearest platform.
This unique holiday village is centred on a shallow man-made lake. Built in the early 1900s houses vary in style, including Tudor, Jacobean & traditional 18th century East Anglian weatherboard. Shingle beaches stretch north and south.
A main street of Georgian houses and older cottages provides a historic backdrop to a wide shingle beach where fishing boats rest up in a long line and numerous fisherman’s huts sell the daily catch of fish and shellfish. By 1600 the town was a prosperous port and fishing centre and in the 19th century it became a popular resort. But things have changed over the years. The half-timbered Tudor Moot Hall, the Town Hall, is now almost on the shore and the three roads that originally separated it from the sea have been washed away over time.
A sedate Edwardian resort stretches around a long, gently curving bay, rubbing shoulders with one of Europe’s busiest container ports.
In the resort part of town a paved promenade is backed by well-tended gardens. Beyond the Spa Pavilion beach huts take the place of the gardens and follow the sand and shingle shore. The pleasure pier opened in 1905, 800 metres in length, making it, at one time, the longest in the UK. It had its own station and steamers operated from the seaward end which was demolished after WWII. The shore end was rebuilt and re-opened in 2017.
