The Mino de Fiesole marble is a marble tabernacle that was once let into the south side of the west wall. It was made by Mino Di Giovanni (1431 - 1486), called de Fiesole. He was born at Poppi in the Casentino in 1431 and had property in Fiesole, hence his name. The sculpture was remarkable for its gem like finish and extreme delicacy of detail. Mino Da Fiesole made the marble tabernacle for the Holy Oils of a church in Italy. It was so lovely that the order was given for a replica for another church.

In the centre is a small painted figure of Christ. The church in which the replica was placed was bombed during the first world war and the original is believed to have been the one in All Saints church, Nynehead. It was sold to the National Museum in Wales at Cardiff for £12,500 in 1970 in order to finance the extensive restoration required for the church at that time. The restoration included completely re-roofing the nave, work on the stonework of the tower, repairs to the south wall and re-wiring the whole church. The total cost of the quinquennial repairs at that time was £11,000.
