Będzin Castle – a medieval defensive stronghold constructed by Casimir I Great as part of the system of the so-called Eagle Nests in the Lesser Poland region, 4.5 km from the borders with Silesia; it was destroyed many times and rebuilt in 1965. The castle is located on a high escarpment on the left bank of Czarna Przemsza River; it is an example of the defensive architecture of the mid-14th century. It was an important link in the defensive system of the western border of Poland. The history of the fortification in Będzin goes back to the 9th century. Eventually, the castle was rebuilt after the Second World War, and in 1956 it was handed over to be the seat of the Zagłębie Museum in Będzin, the first museum institution in Zagłębie (mostly a collection of arms and weaponry from the previous centuries). The stronghold consists of a palace and a vast settlement outside the castle with the remains of the encircling walls as well as the now destroyed gate which was preceded by a drawbridge.
The castle is surrounded with a moat and a high double wall.
