my next stop was a day-long layover in vienna, which i used to take a bus to bratislava, slovakia! the bus ride took about an hour. bratislava has a nice, sleepy old town that was very fun to walk around for a day. i climbed a hill to the city’s castle, with views over the danube river and a bridge with a ufo-shaped restaurant on top of it. there were some nice churches as well. i then crossed the danube to peruse bratislava’s largest shopping mall. the economy of slovakia has recently been doing very well, and slovakia has become a manufacturing hotspot in the european customs union. in fact, slovakia currently produces more automobiles per capita than any other country on earth.
