With Angra do Heroísmo classified as a UNESCO World Heritage Site, Terceira played a strategic role in the 16th and 17th centuries as an Atlantic trading post. Baroque architecture, forts and churches, as well as traditions such as bullfighting and the Festas Sanjoaninas (Sanjoaninas Festivals), make the island a dynamic cultural hub. The island's volcanic interior, notably Algar do Carvão, offers unique geological exploration experiences, while traditional cuisine rounds out the offerings with authenticity.
