Yes, I got that impression about Guinness too, and the more I plot points on a map and read little extracts, the more I realise how much was lost and homogenised.
Here's the entry I have for Drogheda:
"an extensive distillery, and three large breweries of ale and table beer, one of which, in James-street, belonging to Mr. Cairnes, produces ale which is in great repute, and is exported to England and the West Indies; attached to it is a very extensive malting establishment."
This was 1837, but it's possible it was one of those still in operation. In fact, I have mapped the one on James Street, as it was in the 1830s, but a search[/url:1w25qhww] I did for the Castlebellingham & Drogheda Brewery said it was located on Marsh Road in 1931. Marsh Road today lies where the old path of James Street used to be as far as I can tell, so it was probably the same premesis. I just checked on Google Earth, and it looks like there's a scrapyard there now. Look left out of the window of the Enterprise to Belfast as you cross the viaduct, on the south side of the Boyne, and that's where it used to be.
Update: This is slow going. I've only plotted 20 breweries out of abotut 120. <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt="
