The sundial is located on the escarpment near the Old Orangery building in Lazienki park. It has been placed on an uneven surface of a granite boulder (glacial erratic). The monumental piece of rock brought by a glacier was found when then Botanical Garden was established. It is most likely the oldest protected glacial erratic in Warsaw.

The sundial was made by Wojciech Jastrzebowski (1799–1882), a Professor of the Marymont Institute of Agriculture and Forestry. In 1828, he carved out hour lines, date lines, and indicators of the mean solar time on the surface of the stone. He embedded in it an iron gnomon with protrusions, pointing towards the Earth’s celestial pole.
