India has some very good game parks including Rathambore and Kaziranga. They have great temples all over the country, and even grand palaces over and beyond the Taj Mahal. What I found most interesting was that some places in India were settled by people from other countries (besides the Brits) including France, Portugal, and China.
Vasco da Gama is entombed in Cochin in the Church of St Francis.
I was in Portugal recently, and visited the Jeronimos Monastery, but his tomb there is empty.
One can learn much historical trivia from travel.
