I could have stayed in this building for hours rather than scuttling through rapidly on a tour. Every corner, every room was an amazement. Portugal's history - and especially that of Porto, where it all started - is intertwined with trade, colonialism, even slavery and this seat at the heart of capitalism somehow touches it all. The Assembly Room still functions as a meeting room for the trading association that owns the building, while the Arabian Room is used for receptions and high-level parties with heads of state or other VIPs come for a visit, and it's no wonder. Any event would be raised a notch or two by being held here.
The floors of the Hall of Nations in the picture are multicolored mosaics - and are said to be modeled on floors found in Pompei. Best not to be too superstitious though.
I'm told there's a great restaurant in the Stock Exchange... but I can't say because I don't know it.
