In summer 2017, the Italian team erected a Circle of Hipparchus on their school campus. The shadow, usually a circle, becomes a line during the equinox. The incorporated sun dial and the circle itself, its size and inclination, were designed and calculated by the Italian students and teachers. Together they found the perfect spot for the astronomical device and used it for first observations. During the mobility to Italy, the mechanism of the circle was explained to the visiting students and teachers and they had the chance to make their own observations at the equinox, experiencing the mechanism of the circle first hand.
