For such a prominent building in Redcar, information is surprisingly hard to come by, the recently published Redcar and District Local History says it was built in 1869 at a cost of £4000 with seating for 650. That information is sourced from the Bulmers Guide of 1890
There are addition references to hint at both dates :-
Guisborough Wesleyan Methodist Circuit Register Of Baptisms Redcar Section. (1860 – 1926)
Redcar Chapel (Trinity) – Booklet entitled “100 years of Service. Trinity Methodist Church, 1869 – 1969.
Update : Fred Brunskill comments that the earlier methodist chapel was from 1853 and on the High Street where Clinkards now is on the right of this photo.
