Make your way uphill to Parque do Castro via Camelias Street - although the climb is somewhat steep, the views over the Vigo estuary from here are simply unbeatable. The Castro de Vigo (dating back to the 3rd century BC) and Castello the Castro can both be visited en route.

For a superb view over Penang and the Straits, take the funicular railway to the top of Bukit Bendera hill. The ride takes 30 minutes and the summit, 830 m (2,727 ft.) above sea level, is, with an average temperature of 3 degrees Celsius, cooler than the steamy coast.

This beautiful example of Spanish colonial architecture contains a small museum dedicated to the Spanish Inquisition's brutal persecution of heretics once carried out in these very chambers. Visitors can still see some of the torture devices used to extract confessions of heresy and witchcraft, along with some of the questions used in "witch" interrogations, which are still displayed on the museum wall. Needless to say, no prisoner could hope to be acquitted of their purported crimes against the Catholic Church, and most met their tragic end at the very guillotine still on display in the courtyard.
