Munkács Castle played an important role in Ferenc II Rákóczi's War of Independence. On 16 June 1703, the prince travelled from Poland to Hungary via the Verecke Pass. His troops occupied Munkács on June 24, 1703, but they were unable to occupy the castle at that time, although the Rusyns around Munkács persistently helped. The siege of the castle began in November 1703 and ended on February 16, 1704 with the victory of the Kuruc army. Rákóczi immediately moved in and headed for a freedom fight, which was a very important base for his strategic position. He therefore instructed Demoiseaux brigade engineer to prepare a plan for the modernization and reconstruction of the castle. In 1705 he began to strengthen the castle. Most of the work was carried out by Bereg County Hungarian and Ruthenian serfs; it continued until 1710. The construction was first supervised by Colonel De La Mothe, and from 1708, De la Faux was taken over. Next to the castle, the mill on the left bank of the Latorca was converted into a mint in 1706, which operated until 1713.
