After Monday’s post about St John’s Church in Clonmellon, County Westmeath, here is an image of another monument in the same part of the world: the obelisk in the grounds of Killua Castle. It was erected in 1810 by Sir Thomas Chapman to honour the memory of Sir Walter Raleigh who supposedly first introduced the potato into Ireland in 1589; the Chapmans originally came to this country thanks to the support of Raleigh who was a maternal first cousin.
