There's a little local museum next to it, and the LOL (little old lady) at the desk gave me a tour of the local guild banners, which are very rare. She really had the gift of the gab, and seemed to want to tell me the entire history of Ireland, Drogheda and the museum on the side. I presume her family history was next, but thankfully I made my escape when the next party arrived. The only other highlight (????) is the display of historic telephony equipment, which is, erm, probably unique.
Irish Charity shops: they do have them, but they seem to reflect a different era, when there were society ladies, as many of them seem to be named after a particular person (Mrs Greene or whoever), and don't even mention the name of the charity concerned. A strange state of affairs, but then I guess that would have been how many charities themselves started in Victorian times.
and on to Newgrange...
