The Portuguese moved the capital from Old Goa to Panjim in 1843.
Old Goa was the capital of Portuguese India from 1510 to 1843. It was a major center of trade and commerce, and was home to many important Portuguese buildings, including the Church of St. Francis Xavier, the Cathedral of St. Catherine of Alexandria, and the Basilica of Bom Jesus.
However, Old Goa was also a very unhealthy place to live, due to the high levels of malaria and other diseases. In 1843, the Portuguese decided to move the capital to Panjim, which is located on the banks of the Mandovi River. Panjim was a much healthier place to live, and it was also closer to the port of Mormugao, which was important for trade.
The move of the capital from Old Goa to Panjim marked the beginning of the decline of Old Goa. The city lost its importance as a center of trade and commerce, and many of its important buildings fell into disrepair. Today, Old Goa is a UNESCO World Heritage Site, and is a popular tourist destination.
