Religious influence: Catholicism was introduced to Trinidad by the Spanish colonizers, making Trinidad predominantly Catholic. There are many Catholic churches and cathedrals built during the Spanish colonial period that still stand today.
Spanish language influence: Despite English replacing Spanish as the official language of Trinidad in the 19th century, many local words and place names retained their Spanish origins, and some dialects used in the country such as Spanish Kreole include Spanish vocabulary and structure.
Cultural traditions: Various Trinidadian traditions have Spanish origins, including traditional dances like the joropo (a Spanish folk dance) and tamunango (derived from African and Spanish influences).
Place names: The Spanish influence led to the naming of many major towns, areas, and natural elements on the island as such, for example; Puerto Espagnol (Port of Spain); Rio Claro, Arima, Tacarigua, etc.
