Hungary

A Benedictine abbey founded in 996 atop Pannonhalma Hill, where monks established Hungary's first school and preserved the earliest surviving document containing Hungarian words from 1055. With its basilica begun in 1224, a 19th-century library holding over 300,000 volumes, and a thousand years of continuous monastic life, it was inscribed as a UNESCO World Heritage Site in its millennial year of 1996.
