Llanfairfechan Methodist Chapel was built, before 1897, in corrugated iron with a gable-entry plan. The chapel is known locally as 'Capel Sinc' and has a well maintained interior with an organ against the west wall, a raised altar area and stained glass windows. The ceiling is two-thirds timber panelling and the final third, above the altar, is painted blue with gold wooden stars attached.
