1656 - Merchant William Bevan, ‘the first Swansea Quaker’, donates a plot of land stretching from the High Street to the Strand for a meeting house. Over the centuries, this plot will serve for a succession of four meeting houses and a burial ground. The 1st Swansea Quaker Meeting House is built, probably on the Strand.

Early 19th century - Entrepreneurs, many of them Quakers, flock to develop the Swansea/Neath area industrially.

1817 - Joseph Tregelles Price of Neath Meeting founds the Peace Society in London, with a local branch which many Swansea and Neath Quakers join.
1850 - Swansea Meeting has dwindled, thanks in large part to Friends being disowned or forced to resign for marrying a non-member. It survives with help from Neath Friends.

June 1899 - 4th Meeting House opens, on the High Street, with a 5am outdoor prayer meeting. Membership is up to around a hundred, the meeting room (with a gallery) can seat 250, and there is another room for Bible classes. The Meeting is now at the extreme evangelical end of the Quaker spectrum.
