This is a map of all the parishes in the Liverpool area and slightly beyond, as they were in 1851, plus some Anglican churches from the era.
There is scant information at the moment (much taken from David Lewis's excellent The Churches of Liverpool), but this will be added to over time.
When you read when a church was 'built', this might mean it was opened, or completed, or consecrated, depending on the information I have to hand. These events, of course, might all have occurred in the same year anyway.
When I state when it was 'demolished', this might mean it closed that year and no further history is known. It implies the church building is no longer there. Churches which are no longer used for services, but still exist, are not labelled as demolished.
Sometimes I have had to give a year when it is only roughly known, and this is mentioned in the notes.
You can search for a parish using the magnifying glass icon, and click on 'Show churches' see some of the places of worship.
