Horeb Baptist Chapel was built in 1848, with modifications in the later nineteenth and twentieth centuries. The present chapel, dated 1848, is built in the Simple Round-Headed style with a short-wall entry plan and tall small-pane windows. Horeb is now Grade 2 Listed.

Horeb Welsh Baptist Chapel was built in 1848 by John Jenkins as a sister chapel to his ministry in Hengoed. The original building is a square plan gable-ended building with the entrance on the long wall as opposed to the more usual gable end. It is a simple design, with two tall, round-arched small-pane windows to the front. The Chapel interior has a three-sided gallery supported by iron posts, with the original panelled box pews facing the pulpit on the rear wall. 
In the early 1960s, a large Community Hall extension was added to the rear of the Chapel. It is a single storey cross-gabled structure that widens at the north end, forming an uneven T-shape, built in red brick in stretcher bond with a corrugated asbestos roof.
