It was about this time, known as the disruption.that the Rev William Bruce Cunningham along with his followers "split" from Preston Church to form what was to be known as the Grange Free Church.These two churches were to remain as separate charges until 1981, when they united to form the present Prestongrange Church. In later years members of the Roman Catholic faith who had worshipped at the monastery at Drummore, eventually built St. Gabriel's church. (3rd April 1966).

It is also worth recording that around 1917 the Salvation Army came to Prestonpans and finally took up a permanent residence in the then empty Grange Church Hall, while the Grange Church itself is again now being used as a place of worship and is known as The New Saint Andrews Episcopal Church.

In 1899 after years of discussion, a Town Hall was built in Prestonpans.

The two collieries in Prestonpans, Prestongrange to the west and Preston Links to the east, in order to accommodate their increasing workforce, built housing for their employees at "Cuthill" and "Grown Square". Other schemes built to house miners and their families were the tenement building at the bottom of "Robertson Avenue" known as "Honeymoon" also North and South Crescents.

In due time the local council built several new housing schemes, until the fields between "Salt Preston" and Preston were no more, and Prestonpans stretches from the sea shore right up to the newly rebuilt "Colonel Gardiners House" at Bankton.

In recent years local industry has declined. The coal mines are gone, "Prestonlinks" being the last colliery to produce coal in East Lothian.On this site there is now a Power Station. The electricity produce from this station is made by coal partly supplied by the near by open cast coal site, at "Blindwells". The other supplier is Monktonhall Colliery which is owned and worked by a company of miners, some of whom are local men.

And so having survived battles, wars and economic recessions, Prestonpans Town and Church still flourish and will continue to do so for many years to come.
