Redwick is a small village and community (parish) to the south east of the city of Newport, in South Wales.

The ancient church of St. Thomas the Apostle is notable for many unusual features. It is unusually large for a parish church on the Caldicot and Wentloog Levels, perhaps second only in its grandeur to that at Peterstone. The church has a full immersion baptisty (although for how long no-one knows), unique medieval stone carvings and a fine Victorian pipe organ salvaged from two previous churches. On the ancient South porch is a distinctive `scratch post' or "Mass sundial" and (like the church at nearby Goldcliff) has a mark indicating the level of the inundation caused by the Great Flood of 1606.

The handsome font originates from 13th century and may have been an original feature. In the ancient peal of bells, the fourth and fifth are pre-reformation bells from the Bristol foundry, dated circa 1350-80 making them some of the oldest church bells working anywhere in the country. Most unusually, following their lowering in the tower in the 1990s, the bells are rung from the chancel in full view of the congregation, although a number of old unused rope bosses suggest that this must have also been the case at some time in the past.

The fine East window, which contains some painted glass from about 1870, unlike the roof and the other windows, escaped the near-by bomb blast of 1942. The restoration and re-modelling on the church, including the attractive raised tiled floor, in 1875, was by John Norton who later also participated in the building of the exquisite chapel at Tyntesfield in Somerset.
