Earthen ramparts (baby, castle) are the monument of archeologists of national importance in Volodymyr-Volynskyi, which were built in the tenth century in order to defend the castle. The first castle was built in the tenth century. He did not survive. In the second half of the XIV century Polish King Casimir the Great built his castle behind the ramparts. The last documentary mention of the castle in Vladimir dates back to the XVIII century.
In 1831, a prison building was built behind the ramparts. This building was used as an NKVD prison in 1939-1956. Wooden sculptures of the Galician-Volyn princes and the largest wooden princely throne in Ukraine were recently built behind the ramparts.
