The Museum of the Hungarian Language stands at Széphalom, the village associated with language reformer Ferenc Kazinczy. Its exhibitions turn Hungarian itself into the subject, covering vocabulary, writing, regional usage and the cultural work that shaped the modern language.
For Sátoraljaújhely it is one of the more distinctive cultural stops, especially when combined with the Kazinczy memorial house nearby. The site is outside the centre, so it fits best as a short excursion rather than a walk-up city sight.
