Knolton, North Wales
"Peace be within thy walls."
Knolton is just inside North Wales, in what used to be Flintshire (now Wrexham). Primitive Methodist preacher William Fitzgerald preached there at least as early as January 1833, as reported in the Magazine of that year (page 433). The chapel is still in use. It was opened in 1868, and the extension, discernible by the different shade of brick, was added in 1904.
The text on the outside wall, seen in the upper white rectangle, is from Psalm 122:7, “Peace be within thy walls.” Here of course is a double reference. A Methodist congregation should be a context in which people are at peace and harmony with each other; it should also provide an environment in which people learn to experience that “since we are justified by faith, we have peace with God through our Lord Jesus Christ” (Romans 5:1).
