Prague is a picturesque city beloved by photographers—and by Condé Nast Traveler readers, who voted it their sixth favorite city in the world last year. And while much of Prague’s art and architecture is several centuries old, its attitude is decidedly progressive, particularly when it comes to LGBT rights. The city is home to August’s annual Prague Pride, which was first held in 2011; and the long-running, multi-city Mezipatra Queer Film Festival that serves as both showcase and gathering place for international artists each fall.
