As I continue to catch up on the large number of things I did in Portugal from, now, *several*…read moremonths ago... this is the one review I have left that is probably the least likely to have changed in a few months, of a building whose main attraction is the beauty of the building itself, beauty that was all constructed... not recently. Though I did also appreciate the tour, mainly in the history of the building, a building honoring not a king or a royal line like the other glamorous historical building we stopped at earlier in the trip, the royal palace in Madrid, but the history of commerce itself in the country, and the continued independence of a small nation surrounded by Spain on several sides, mostly on the power of their *money*. Money, which of course, they also used to construct this impressive building, that *reminds* you of a building a historical king would construct to honor his own family with stolen riches, but in this case, the riches seem to have been earned more... legally, at least.
It is still also used at least sometimes for its original purpose (impressing foreign businessmen, i.e. business meetings), but obviously now mostly for our purposes it's a spot on all the tourists' list of half-hour tours. Definitely worth a stop if you're never been - though it is too bad tickets sell out somewhat in advance, in that I bought 2 tickets to this weeks earlier, not counting on my wife to be feeling rather sick that day and unable to join a tour. I don't think tours are unreasonably priced, given it's a unique, historical, and quite impressive building, but it was definitely not worth it at the effective twice the cost it ended up being when my wife couldn't make the tour. That said, you don't have to reserve the *time* in advance, though as other reviews have pointed out, if you only speak English, they have tours in 3 languages, so you want to get there relatively early the day of your tour, and redeem your tickets, valid for any tour the day, for passes, valid for a specific tour, before all the spots on the *English* tours are taken. They do have tours all day, though.
At the end of the tour, they also have a small, presumably subsidized, shop selling pastel de nata, glasses of one specific bottle of Port, and espresso. I say presumably subsidized because, even by the standards of food and drink in Porto, already somewhat better than in the US, all three of those items were... inexpensive, and solid. Obviously that isn't why we went on the tour, but I did have a goal of trying as many of all of those as I could in the time I was in Portugal, so it was a fun bonus.
