The Victorian Holy Trinity is known as the ‘new church’ to distinguish it from the partially ruined old church.
Elsecar was mainly a farming village until coal mining came to the area. Elsecar Old Colliery was built in 1750 and the New Colliery was opened in 1795.
The increased industry in the area produced a need for housing and rows of cottages were built by the 4th Earl Fitzwilliam of Wentworth Woodhouse who owned the local mines and ironworks. On Whit Monday in 1841, the 5th Earl Fitzwilliam laid the foundation stone of the new Anglican church for Elsecar. It took 2 years to build and cost the Earl £2,500. It was consecrated on Whit Monday 1843 by the Archbishop of York and has changed little over the years. It is built of sandstone, roofed in slate and designed in the Early English architectural style.
The four stained glass windows were installed in 1920 to commemorate parishioners killed in the First World War. They are by Morris and Co London which was founded by the preRaphaelite artist and designer William Morris. The windows are very striking and portray several bible scenes. The first depicts David and Goliath. The next shows Christ in crimson robes, with a panel underneath showing the raising of Lazarus. The third shows St Sebastian pierced with arrows and St George slaying the dragon and the last depicts St Michael trampling on Satan under his feet and a panel showing the raising of dead warriors.
