Churches in Goa are some of the oldest structures existing since the time of Portuguese invasion. Most of them also reflect the Portuguese style of architecture and acclaimed by world tourists. These churches are most visited during the Christmas when it is a carnival in Goa. Churches here are lit with colored lights and dominate the landscape of Goa. The most prominent ones are Basilica of Bom Jesus, Se Cathedral, Church of St Francis of Assisi and Chapel of St Catherine.
