Berthlwyd Baptist Chapel was built in 1851 and then re-built in 1880. The later chapel was built in the Simple Vernacular style with a central entrance in the gable wall. The chapel has two storeys with stairs either side of the entrance. The pulpit is to the rear of the chapel and the doors either side of it that lead to a hall. The Hall has a sliding room divider enabling multi uses of the space. There are also two external entrances to this hall, one either side of the chapel building.
