Prague in $460s-$550s RT

It's true, castles are a dime a dozen over in Europe. But this towering behemoth really stands out from the crowd.

Welcome to Prague Castle, a fortress so big it has its own district. Within this complex (the largest castle complex in the world) lies the royal palace itself, an enormous medieval church, another enormous medieval church, a painting gallery, two royal gardens, and a ton of old buildings—including Franz Kafka's former digs.

Oh, and it looks incredible in the snow :-)

P.S. As you stroll among Prague's medieval buildings, keep an eye out for old house signs. In the days before Google Maps (or even street addresses), homes and businesses were identified by these intricate wood and cast iron symbols hung above the door. See how many you can spot!
