Construction of Moti Daman Fort began in 1559 by the Portuguese, primarily to defend against attacks from local rulers and other European powers. It was built over several decades, with additions and modifications made over time. The fort served as a crucial strategic outpost for the Portuguese during their colonial rule in India, protecting their trade routes and interests in the region. It witnessed several historical events, including sieges and battles. Today, it stands as a testament to the Portuguese influence on Daman's history and architecture.
