There is a municipal playground next to the Santok Castle Museum, where Little Archaeologist workshops are held as part of educational activities and where visitors can rest while waiting for the ferry crossing over the Warta River. There are two realistic sculptures of rhinos there, and a 1:1 scale plastic skeleton of this animal is located in the sandbox and is an additional attraction of "Sandtown". This installation refers to the 2016 discovery made near Gorzów. At that time, the best-preserved skeleton in Europe was found of a rhinoceros of the species Stephanorhinus kirchbergensis, which lived in these areas 125,000 years ago.
