“At blacksmith’s home, wooden skewer”, so says a portuguese proverb.
What does it mean? Let me give you an example.
Santarém is commonly known as the portuguese capital of Gothic. Since the old Scalabis has a bishop, it also has a cathedral - a Gothic one, you might think… but no: the cathedral is not even medieval, since it was built between 1647 and 1711; so, the main temple of the capital of Gothic is actually Manneirist (with a few glimpses of Baroque).
Never expect the obvious to be obvious.
