The name "Spiš" was derived from the name of the local castle (Spiš Castle) that dominates in this region. It was built already in the 12. century. It stays on ruins of a former Celtic (later Slavic) hill-fort that had existed here already a long time before. Its surprisingly large area and a monumental architecture makes it the second largest castle in the Central Europe and one of the largest castles in Europe. It was a seat of the most important feudal lords of the Spiš region.
