Centuries as the capital of a huge empire left a remarkably rich legacy in Vienna. Palaces, castles, cathedrals, museums, opera houses: the city has an embarrassment of cultural sites, that are invariably beautiful and (from the perspective of a 5 year-old, mostly) interesting. Particular highlights were the Stephansdom Cathedral, and the Kunsthistoriches Art Museum (which happened to be air conditioned, providing a little added incentive in the 35 degree heat).

It’s a total treasure-trove. We could have spent weeks without getting bored or running out of options.
