Former Welsh Congregational Union Chapel (Eglwys Y Tabernaacl)

The former Welsh Congregational Union Chapel, also known as Eglwys y Tabernaacl, is a Congregational chapel built in 1854 by Henry Hodge. It is constructed from Kentish rag stone, featuring copings of Caen stone and window tracery made from Ransome's patent siliceous stone, topped with a gabled slate roof. The chapel is designed in the Gothic Revival style, showcasing Perpendicular elements alongside early Decorated features.

The east gable includes a wheel window with a central quatrefoil, while the west side features a three-light window with graduated ancets. The six-bay side walls are marked by tall offset buttresses that separate tall two-light Decorated windows. The King's Cross Road elevation has moulded pointed-arched doorways flanked by engaged shafts and two-light trefoil-headed basement windows. The Pentonville Road elevation features a double-gabled west porch from around 1870, which includes moulded pointed-arched doorways in front of a two-storey bay with a two-light trefoil-headed window.

Inside, the chapel is well-preserved, retaining its original pews and fittings, including blind Gothic arcading around the organ pulpit and a raised balcony at the front. The gallery, added in 1857, has Gothic arcaded fronts supported by cast-iron columns with decorative brackets on the west side. The six-bay hammerbeam roof is supported by angel-carved corbels and features cusping in the spandrels.

Historically, the chapel was transferred to the Welsh Congregational Union in 1889, and between 1904 and 1940, it was served by Howell Elvert Lewis, a notable poet and hymn writer.
