Batthyaneum Library

The Batthyaneum Library occupies a former Trinitarian church building with high ceilings and long shelves where volumes are arranged in the central Aula Magna hall. The space houses a substantial collection of historical documents, including medieval manuscripts and archaeological artifacts.

Bishop Ignatius Batthyany founded the library in 1784 by converting a former military hospital into a center for literary studies and astronomical research. This transformation marked the beginning of an institution dedicated to preserving and studying important historical works.

The collections display medieval manuscripts and early printed books that visitors can view within the historic rooms. The Codex Aureus, written in gold ink, stands as one of the most valued pieces and shapes the character of this collection.

Visits require advance registration, and researchers need formal approval to access the substantial collection of historical documents. It is advisable to contact the institution beforehand to plan a visit and clarify the specific requirements for using the archives.

The library preserves half of the Codex Aureus, while other parts are distributed between the Vatican Library and museums in London. This division makes the manuscript a rare example of a significant medieval work housed across multiple locations worldwide.
