It was probably built in the initial period of the Duchy of Cieszyn, established in 1290, on the orders of its rulers. Its existence as a fortress is first confirmed in the feudal certificate of Duke Casimir I from 1327. At that time, it was probably a wooden structure surrounded by wooden and earthen ramparts and moats, designed to guard the nearby trade route from Cieszyn through a ford (later a bridge) on the Vistula River to Bielsko. The stronghold was probably expanded in the 14th or early 15th century. Starting from the 15th century, the Dukes of Cieszyn increasingly stayed there, often issuing important documents there, e.g. the so-called great privilege granted to the city of Bielsko by Bolko I in 1424. From 1431, the castle was one of the seats of Duchess Ofka, then it was the seat of Duke Przemko II. In the years 1573–1577, Skoczów, together with Strumień and the surrounding villages, was sold by Duke Wenceslas III Adam, creating the Skoczów-Strumień estate state. Its new owner, Gottard (Jerzy) from Łagów (von Logau) in Stara Wieś (Altendorf), began rebuilding the previously wooden and earthen castle into a brick one. Gottard died in 1589, but the reconstruction was continued. In the following years, the castle lost its defensive value, taking on a residential form. After the estate state returned to the Duchy of Cieszyn, around 1594, the castle became the seat of the burgrave and, from the beginning of the 17th century, of the hetman, managing the Skoczów-Strumień key of goods (the so-called state).
