When I visited Knowth in the end of the 1990's, they were still excavating the big mound, so I took most of my photos on the smaller satellite-mounds. According to the little guidebook I bought, the small mounds are older than the big one.That's strange, isn't it ? Building a big one so close to the smaller ones, that a couple of them are almost joined together with the big one. The reason to build it right there must have been astronomical : there are two passages into the mound and both of them are aligned with the equinoxes. The eastern passage is 40 meters long, making it the longest megalithic passage in Western Europe.

Like Newgrange, there are kerbstones all around the mound, and here you can take a look at them one by one.
