The first written mention of Skalica comes from 1217, when it is mentioned under the name Zakolcha. At the beginning of the 14th century, it first became a free market settlement, and in 1372 king Louis I of Hungary granted it the rights of a free royal city. Soon, the construction of the city walls began. The construction of city defensive walls was completed around 1435. In the eighteenth century, fortyfications lost their importance and were gradually dismantled.
The ring of stone defensive walls was about 2000 meters long, the height of the wall reached 8 meters, and the thickness was 1,8 meters. Their upper part ended with a guard sidewalk and battlements. Two main gates led to the city: Holíčska and Strážnicka, and two smaller ones: Severni (North) and Jižní (South). In addition, there were two wicket gates within the walls: Upper and second at the municipal tower. In the fifteenth century, the rotunda of St. George, standing near the northern wall, was superstructured and gained defensive functions.
To this day, the remains of the Northern Gate and several sections of the walls have been preserved. The best preserved fragment is located in the area of the Franciscan monastery in the south – eastern part of the city. In addition, significant fragments are found in the north-western part near the rotunda of St. George.
