My wife and I will be in Finland's third city Turku for at least one night in mid-July, and I was wondering if FT has any interesting suggestions for places to see, do or eat nearby. I've briefly stopped in the city a number of times, but it's probably been >10y since I was last there and I only have vague memories of being underwhelmed by Aboa Vetus, reasonably impressed by Ars Nova and not too impressed either way by the Hansa shopping centre. I'm also reliably informed that I have been to the castle and probably the cathedral as well, but I'll be darned if I can remember a thing.

We're tentatively staying at the apparently fairly central Holiday Inn on points. If the weather is suitable, a quick cruise to Naantali and possibly even the dreaded Moominworld might be on the agenda. Any other ideas?
