Engedi Welsh Calvinistic Methodist Chapel built was built in 1842, rebuilt in 1867 and modified in 1890. The present chapel, dated 1867, is built in the Classical style of the gable entry type, to the design of architect Richard Owen of Liverpool by Evan Jones of Dolyd and cost £4579. The Classical front is of granite masonry with Penmon stone dressings and a portico.

The interior is particularly fine, with an octagonal pulpit within an unusal Set canu, a large set fawr, and an organ within an ornate argan arch heavily decorated with Classical detailing including Corinthian pilasters and swags. The raked galley is on three sides and is supported by cast iron columns with brackets and foliate capitals. The ceiling consists of 15 square panels, again very heaviy decorated with classical mouldings and with ornate roses to the centre of each providing ventilation and fittings for lights. The basement has a ministers room, offices and schoolroom. The chapel is now Grade II listed.

On this site in 1856 the descision was taken by a group of Nonconformists to establish a settlement in Patagonia.

The chapel was sold at auction in April 2014 for £45,000 after having been disused for a number of years. At this time the interior, inluding the organ, pulpit and pews were intact.
