Sadly i can't find any photo's but this is from The Irish Whiskey Trail archive.
The entrance still exists and has recently been renovated.it has casa rio over it. Rio which refers to the river that flows near it which would also have been used in the distillery. Casa Rio translates as River House
I have read that Casa Rio refers to the Pierces' HQ in Argentina.
I believe that it was named that in the Devereuxs time too so this may be questionable. I hope to come up with answers in time.
