2009, with the committee concerned about the proposed new extension (terming it "inappropriate"), although recognising the "high heritage merit" of the proposal. Cadw (the Welsh Assembly Government body responsible for the built heritage of Wales) made a grant of £150,000 in 2007; the National Churches Trust made a grant of £10,000 in June 2010; and other bodies and individuals made donations to the appeal. The church reopened after its restoration on 1 May 2011 with a Mass celebrated by the Bishop of Wrexham, Edwin Regan. Architecture and fittings Built of reinforced concrete, the building is designed in the style of an upturned boat, and the design has a "nautical theme" with elements such as porthole windows. This is a deliberate reference to Amlwch's history as a port town and its position on the coast. The church has six concrete parabolic arch "ribs" along the outside, with portholes on the base plinth between each rib. The main entrance is at the south end of the church at the top of some stone steps on either side. A window (shaped, like all the others in the church, like a star) set in mosaic is positioned above the door, and there is a stone cross at the top of the facade. The concrete of the church is dressed with stone on the south side, nearest the main road. The ribs on the outside are visible inside the building; in between them, there are patterns of lights and coloured marble panels on the lower parts of the interior walls. The vestry is to the rear of the church, and there is a parish hall, built from masonry, underneath the church. The altar was replaced in 1995 and again on the reopening of the church in 2011, when a carved crucifix, which was brought to Amlwch from a former convent in Liverpool, was also dedicated. The porch houses a sepulchral slab, dating from the latter half of the 13th century. Assessment The church is a Grade II* listed building – the second-highest of the three grades of listing, designating "particularly important buildings of more than special interest". It was given this status on 12 December 2000, and has been listed as "a remarkable inter-war church". Cadw describes it as "striking and individual", and "a highly unusual and experimental design which exploits the plastic qualities of its constructional material to create a powerfully expressive religious building."
