 The four pillars were first made of wood put proved to be not strong enough to hold the large and heavy marble altar and so the pillars were changed to be made out of marble.The layout of the church from 1810 onwards has remained largely unaltered.However, in 1908 a full refurbishment of the Long Tower took place which included addition of new stained glass windows, statues, shrines, baptismal font and the reposition of the High Altar and the introduction of a new sacristy.
