Most parts of the palace were explored and restored in the period between 1934 and 1938, but even today there are archeological excavations in progress. Passing through the narrow stairs, alleys, under arches and gates built in Romanesque style, a part of the past seems to come to life. This part of the palace was built in the time of King Béla III. With his wife - the daughter of Louis VII - French architects arrived and constructed the late-Roman and early-Gothic building at the end of the 12th century.
