The origin of the castle is uncertain. It was first mentioned in the mid-15th century as owned and probably also built by the Vezsenyis. Past 1472 King Matthias I donated the castle to his loyal General Pál Kinizsi who considerably extended and fortified it strengthening walls, digging a moat, building a chapel, a multi-level keep and a barbican.
By today it is only the 4-level keep that demonstrates its past glory. The exhibition rooms of the tower offer an insight into daily life of medieval times: the prison (ground floor), the guards’ room (first floor), the knights’ room (second floor), the ladies’ room (third floor) and archeological finds from the heyday of the castle (fourth floor). A stone collection, the chapel, a coin press machine and a weapon exhibition each contribute to the medieval experience.
In summers the castle is home to Medieval Games with martial shows twice a day (at 11.00 and 15.00, from July 1 to August 20).
Nagyvázsony offers an alternative program opposite of the castle with the Museum of Postal Service featuring devices of telecommunication from the 19th century until today (trying the Mickey Mouse telephone is a must for kids.). Another option is to visit Schumacher House, an open air museum of ethnography. On the hill behind the castle there is a white evangelical church with an equestrian statue of Pál Kinizsi. His marble tombstone was placed in the castle chapel.
