All Saints on Nuxley Road and Erith Road. The church opened in 1853, but wasn't finally completed until 1861. TQ 4926 7829. From an old postcard view in Reg Dosell's Collection. A 2020 Streetview provides another view. Link. Grade II listed.

Belvedere Baptist Church is on Nuxley Road, and was seen by Streetview in 2021. There was a Baptist Chapel on the same site showing on a map of 1870, though the present building looks considerably newer. TQ 4908 7811. Link. The same 1870 map shows another Baptist Chapel a little further to the S.W. at TQ 4899 7796. This is now Free Grace Baptist Church, seen by Streetview in 2021, where can be seen the date of 1805.

Belvedere Methodist Church (2020 Streetview) is on Picardy Road at TQ 4945 7889. Marked on older maps as Primitive Methodist, it's dated here to 1876. Link. Google indicates that a church called Loveworld Belvedere (aka Christ Embassy) meets in the church hall behind the Methodist.

Post-dating the 1870 map, and pre-dating one of 1897, is a Congregational Chapel, on Woolwich Road at TQ 4871 7830. It had gone out of use before or soon after 1950 and has since been demolished. Housing now stands on its site, seen by Streetview in 2021. The present Belvedere and Erith Congregational Church is on Picardy Road, seen by Streetview in 2018. TQ 4931 7857. Link.

St. Augustine of Canterbury is on Gilbert Road and St. Augustine's Road, and was seen by Streetview in 2021. TQ 4904 7909. Link. The history page dates it to 1915-16. It was successor to a "tin tabernacle" of 1884 which old O.S. maps show to have stood a short distance away on St. Augustine's Road at TQ 4900 7904. The house on its site today was seen by Streetview in 2019. Moving alittle to the left shows the church and its car park, the site of the Sunday School, contemporary with the first church.
