The institution

About us

Teletár is the preserver of the telecommunication equipments of the Telecommunication Heritage of Szeklerland Association. The collection was donated to the association by engineering professor Ernő Csáky.

The Institution continuously collects, restores and displays old radios, TVs and other telecommunication equipments with the purpose to expand the initial collection.

The Telecommunication Heritage of Szeklerland Association was founded in the spirit of preserving the heritage. The founders undertook the maintenance responsibilities of the entire collection.

The Institution’s main goal is to collect, identify, catalogue, store, preserve and display the equipments and artifacts that have played an important role of the evolution of telephony and telecommunication.


"Let us cherish our memories, therefore gather them so as not to have them lost forever, and thus the past be more empty, the present be poorer and the future be more uncertain."

Arnold Ipolyi



The Showroom is an interactive exhibit offering hands-on visitor experiences by allowing the guests to try the displayed equipment.

The Training Room hosts electronics courses for beginner and intermediate groups, covering theory (getting to know basic equipment – measuring instruments, generators) and practical skills (soldering, error checking) as well. 

The training room also hosts the various small group activities, like presentations, workshops, classes, school field trips, science movies and documentaries, experiments, Morse code courses, amateur radio activities, DIY electrical work, repairing of home appliances, or – by arrangement – the organization of other technical activities.

The Library contains our textbook collection, which can be browsed on-site or borrowed upon request. The archives of the former local television (STV) are also stored and digitalized here. Old discs, audio- and videotapes can be listened to and watched in the Library.
