Glagolitic is the oldest Slavic alphabet, predating Cyrillic, and Vrbnik is one of its last surviving strongholds. The script appears carved into lintels, gravestones, church walls, and public monuments around the old town — a remarkable survival from a period when most of Europe was standardising its written languages.
The inscriptions are not labelled or interpreted for tourists, which adds to the impression of stumbling on something genuinely ancient rather than curated. If you want context, a small collection of documents and printed materials on Glagolitic history is kept at the local archive in the old town hall. The Church of Our Lady of the Angels, the main church in the old town, has several examples of Glagolitic stone carving around its entrance.
