Nebo Welsh Independent Chapel was built in 1808 for a cause founded in 1805; it was later rebuilt in 1835 and 1914. It is in the sub-Classical style, with rendered exterior beneath a hipped slate roof with bracketed eaves. The front facade has three bays, divided by pilastered round arches; the central giant arch encloses a plaque and paired windows over a pilastered arch entry, flanked by tall round-headed windows. The side elevations each have four bays with round-headed windows to the upper storey, segmental-headed windows below.
