John Wesley came to preach in the town, firstly in 1779, and four more times in later years, and a larger chapel was built in Weirhead Street as Wesleyan Methodism grew.
Finally, as this chapel proved too small, the present church was designed by George Vaughan Maddox, a local architect who had worked on The Hendre.
The Reverend Peter Mackenzie was employed as preacher and he drew a large following; he had a personal relationship with many Methodists, whilst his sermons were filled with "grotesque descriptions and extremely funny stories".
A lady visitor, Mrs Bullock, commented whilst waiting for the minister to arrive for the service that she would buy an organ if ever the church was full.
[6] This church is considered to be one of the most architecturally distinguished Methodist chapels in South Wales with an interior that reflects its purpose and design.
