Experience history first-hand by walking right through it.
When the plague hit, the Portuguese had to shift the capital from Velha Goa to Panjim.
They began establishing domiciles with Fontainhas area and then eventually expanded.
Latin Quarters were established by a Goan expatriate Antonio Joao de Sequeira who converted his coconut plantation for this. Hence Panjim became Nova Goa and pretty houses sprung in the Latin Quarters.
Why are they so bright and pretty? It’s simple. Goans wanted their homes to be colourful and those were the only colours they had back then.
