Nejužší pražská ulička, also known as "the narrowest street in Prague," is a super tight alleyway that's so narrow it needs traffic lights to manage the flow of people. It's like a real-life game of human Tetris! You'll find this quirky spot near Charles Bridge, and it's so narrow that even folks in XXL clothes might struggle to squeeze through. It's a fun little detour off the beaten path in Prague, perfect for snapping some unique photos and experiencing a slice of local charm.
