Nestled on the southwestern coast of Ternate, Fort Kastela, or Benteng Kastela in Indonesian, stands as a weathered testament to the early colonial ambitions in the Spice Islands of Indonesia. Constructed by the Portuguese in 1522, it holds the distinction of being the first colonial fortification in the region. Known by various names such as São João Baptista de Ternate or Fortaleza de Ternate in Portuguese, Ciudad del Rosario in Spanish, and Gammalamma in Ternatean and Dutch, it reflects the diverse cultural influences that have shaped its history. Today, it is affectionately referred to locally as Kastella or Kastela, embodying a rich tapestry of heritage amidst its crumbling walls and ancient stones. As a poignant relic of Indonesia's colonial past, Fort Kastela continues to intrigue and inspire visitors, offering a glimpse into a bygone era of exploration and conquest.
