Frýdecký zámek is originally a Gothic castle located at Zámecké náměstí (Castle Square) in the town of Frýdek-Místek. It was built by the Teschen Princes from the Piast dynasty and underwent several architectural modifications over the years, transforming it into a Renaissance and Baroque castle. It changed ownership among various noble families, including the Bruntál family of Vrbno, the Oppersdorf family, and the Pražma family of Bílkov. The last private owners were the Habsburgs, and in 1918, it became state property. Today, the Frýdek Castle houses the Beskydy Museum with an extensive exhibition documenting the history and culture of the Beskydy region. The building regularly hosts various exhibitions, concerts, theater performances, weddings, and dramatic shows.

The first mention of Frýdek Castle dates back to 1327 when it was commissioned by Teschen Prince Kazimír I of the Piast dynasty. The castle was strategically situated on the Ostravice River, which formed the border between Moravia and Silesia. It served not only as a guardian of the regional border but also as protection for the newly emerging town of Frýdek, which was founded concurrently with the castle. The Old German terms vriede (fortify) and Ecke (promontory) also gave the castle and the town their names, Friedeck. Due to frequent reconstructions of the castle, its original appearance is not known, but it is likely that it was a single-story building with a tall tower. Access was through the castle gate over a moat. Ownership of the castle changed hands among several Teschen Princes, and it was first put into mortgage by Václav I during the Hussite Wars in 1434. Various mortgage holders changed during the 15th and 16th centuries. Frýdek returned to direct ownership of the Teschen Princes Boleslav II and Kazimír II, who oversaw modifications emphasizing the castle´s defensive character during the second half of the 15th century. In 1545, Jan of Pernštejn, known as Bohatý (1487–1548), and later his sons, became the mortgage holders of Frýdek Castle.
