This is a Multi Cache. There is nothing hidden at the posted coordinates - they are for the Raglan War Memorial - and to find out where the cache is hidden you need to look at the War Memorial to get some numbers.
The Raglan War Memorial commemorates the good men from three parishes who lost their lives serving their country in two World Wars. Count the losses for each parish to get the numbers:
A=Raglan 1914-18; B=Llandenny 1914-18; C=Penyclawdd 1914-18; D=Raglan 1939-45; E=Llandenny 1939-45; F=Penyclawdd 1939-45.
Use this formula to work out where the final cache is hidden:
N51 45. (C+D) (A+F) E W002 51. C A (D+F)
