9. Megalithic Art Capital
Believe it or not, but Ireland actually happens to be the megalithic art capital. Around 70% of the country’s valleys are covered with megalithic art. One of the most recognizable styles of megalithic art is the spiral motif that is seen throughout the British isles. One researcher has even dared to say that the motif might be in line with some spiritual consciousness, such as those associated with shamanic practices.
