This sundial is one of the most significant elements of the agricultural and livestock past of Madarcos. The sundial is marked with notches that indicate the different times, and in the middle it has a stick that produces the shadow. The time was the time of use by each neighbor of the water of the reguera (natural channel conditioned by man that collects water from streams and springs). These times were distributed in time slots as follows: morning, morning, afternoon, afternoon and evening. These times were controlled by each neighbor, having its water court in the church, where the lawsuits derived from its use were settled. <span class="automatic-translation-warning">This text was automatically translated.</span>
