The name of the Palace Tower, which rises picturesque in the southern part of Detinets, is incorrect. In ancient times, it was called differently: "at the grain yard," "by the bread yard," or "opposite the store yard." It would be logical to name it Grain or Bread, but local historians decided otherwise. The Palace Square, the name they assigned to the tower, did indeed exist in Detinets, but it was located elsewhere, near the Spasskaya Tower. The only justification may be the presence of unusual luxury for such a structure, frescoes in the arches of the embrasures. However, these decorations do not correspond to the palace style, representing only combinations of triangles, rhombuses, circles, and other simple shapes. In the 19th century, the Palace Tower was used for quite mundane needs: it housed the archives of the court chamber and treasury. There were plans to open a skipper school and a shipping museum there, and to use the tower itself as a lighthouse, as it is visible from afar. However, these plans were abandoned due to the need for reconstruction.
