The fourth day was sent in the neolithic. Visited a center where there were several tomb complexes- Knowth and NewGrange - both built about 3000 BC. All had been restored to their original appearance. In NewGrange you could go in to the center of the complex and there was a demonstration of how on the winter solstice the sun would appear in the chamber. I entered a lottery as well - they let 20 people into the tomb on the five days around the solstice to witness the sun's appearance - that is, of course, if it's not cloudy... which it will probably be. Ended to day looking for a food festival in Drogheda, but it turned out to be a gritty city and the much publicized festival was just a bunch of restaurants having special meals. Again had difficulty finding the B&B and looked for over an hour until I was directed down a very narrow and bumpy road to a hotel sized B&B.
