The main WW1 and WW2 memorials are located inside the church of St Peters, but the church does have extended opening times. If it is difficult to visit the church, then detailed and expanded information can be found on the Portishead Town Council (PTC) website, along with details of other memorials in the town.
The link below will take you to the PTC website AND a printed Book of Remembrance is available in the Portishead Library. Having Remembrance Memorials in digital format does give the opportunity to add 'post WW2' and future service personnel to be remembered in the same place for all to find AND the opportunity to add extra detail to an individuals record eg Photo. To add, or amend, detail will have to be done by contacting Portishead Town Council directly.
Pictures of the Portishead War Memorials will be found on the Portishead Town Council website.(link below)
