Built in 1903 on tin-mining riches, this beautifully preserved Sino-Portuguese mansion should make any antique lover's list. Others might find the four-poster steel beds done up in Victorian lace a bit gaudy. But the atrium foyer with its arch-framed koi pond, gorgeous Italian ceramic tiles, blue-and-white-shuttered windows and vintage black-and-white family portraits going back generations are historical details that make visits incredibly rewarding.
