The mysterious pillar in the Zielonka Forest, also known as Światowid, is an intriguing wooden object with a square cross-section (30 cm) and a height of over 2 meters, located along the road from Zielonka to Tuczno. Its purpose remains unknown to this day, giving rise to numerous hypotheses regarding its history and function. Architecturally, the pillar stands out for its simple, minimalist form, blending seamlessly into the natural surroundings of the forest. From a cultural perspective, possible interpretations include a religious function—such as a base for a statue of St. Lawrence or St. John of Nepomuk—or as a commemoration of local events, such as the cholera epidemic of 1848, when residents sought refuge in the forest. Historically, the pillar may also have served as a boundary marker during disputes between the parish priest Gurowski of Gniezno and the Gądkowski family between 1773 and 1775, when the village of Zielonka marked the border between their estates. An interesting aspect is the pillar’s association with the figure of Światowid, suggesting that a four-faced head might once have been attached to its top. The object is fenced and roofed, protecting it from the elements. A popular cycling route, the Duży Pierścień Rowerowy (Great Cycling Loop), passes nearby, making the pillar a destination for nature lovers and tourists. Its mysterious nature captures attention, making it part of the local heritage and a source of inspiration for many theories and legends.
