Atop Armagh Astropark's Hill of Infinity
sits the Stone Calendar. Based on ancient stone circles, it allows us to
tell the time of year by the direction of Sunrise and Sunset.
Imagine that all history is compressed into one year.
Humans evolved only an hour ago, so two more circles have been added: the
middle shows the last four days, and the inner one the final minute of
December 31st.
