The Angra do Heroísmo Museum is housed in the restored Convent of São Francisco, a 16th-century Franciscan complex that occupies a full block in the heart of the historic city. The collection covers the history of Terceira and the Azores across four floors: Azorean decorative arts, paintings, furniture, military artefacts, and a section on the natural history of the island.
The standout pieces are the azulejo panels and the collection of Azorean gold and silver ecclesiastical objects. The section on the earthquake of 1980 — which destroyed or severely damaged about a third of Angra's historic buildings — is sobering, and the subsequent reconstruction effort is well documented. The museum is one of the better regional museums in Portugal outside the major cities. Open Tuesday to Sunday; closed Monday.
