On a recent visit to Liscannor it was possible to view at least three plaques in the town in honour of the famous scientist and engineer:
One near the church:
One on the main street:
and one marking his birthplace on Holland Street (formerly Castle Street):
As if that wasn't enough, the town will unveil a further memorial (pictured below, under construction) on August 31st to mark 100 years since his John Philip Holland's death.
Possibly the most densely commemorated scientist in Ireland, and deservedly so!
