Both photos are thanks to Russell Walker/Facebook combined with his usual well researched information.
1/ The double Swing Bridge and Lock Gate at Lowestoft which opened in 1830. Commercial Road to the left and trees where Station Square and London Road North will be are a part of the Grove Estate. The bridge-keeper's house in the foreground right with the Icehouse behind it. Photo was taken 1880s/early 1890s at a guess.
'First bridge was a double swing bridge and originally opened with tidal flood gates that gradually eroded with Teredo worm and failed, making fresh-water Lake Lothing into a salt-water estuary. There are accounts of thousands of freshwater fish dying and floating on the surface when this happened.'
2/ The Rectory (Vicarage), Stirrups Lane, Corton. 1920s/1930s at a guess. A most impressive building on all accounts, having been built in the early 1840s, and became part of Corton Caravan & Chalet Club, owned by Brian Potter. The Rectory was in-effect destroyed by a probable act of arson in March 1990. The site is now part of the Corton Wastewater Treatment Works. Note St. Bartholomew's Church tower to the right.
