The earliest uses for granite were for paving and for its acid-resisting and fire-resisting properties.
In Trinity College Dublin there are receipts for granite used in paving, for the brewhouse, in the ‘boggs’ and for construction of the ‘stewholes’ and fireplaces in the kitchens.
The earliest of these receipts is dated 1701 and reads:-
Received from Mr Claud Gilbert,
Bursar, ye fumme of five pounds one
shill & three pence on account of
pavers work at New Court_________
The Trinity College receipts, along with other evidence, has allowed me to identify the earliest West Wicklow granite quarry used to supply Dublin, located at Baltyboys, and its operator - the Reilly (Riley/Reyli) family.
For more information refer to my article in the Autumn/Winter 2014 edition of History Ireland - Granite as a building material in Dublin in the early 18th century, by John Hussey.
It is available on JSTOR or as a back issue from History Ireland.
