"Grander inside and out than many of the other buildings by Renaissance architect Andrea Palladio, Villa Almerico Capra, a domed hilltop villa, is a must for architecture buffs and anyone who loves a good house tour. There's no need to book in advance, but opening hours are mind-bogglingly complex: It's open year round, Tuesday through Saturday, for a few hours in the mornings and in the afternoons, but the interior is only open on certain days from March to November. When in doubt, check the villa's Facebook page or contact a staff member through the website." - Andrea Whittle
