"What's the deal with this place?In hyper-dense Hong Kong, it's rare to find pre-World War II buildings that haven't been razed or modernized. But Blue House, a Grade I historic building, has stood the test of time. The name is a bit of a misnomer: It's not just one house, but a cluster of four interconnected tong laus (tenement-style residences and shophouses, once prevalent in the 1920s) in a rainbow of shades—blue, orange, yellow, and gray. The Blue House is the most famous, thanks in part to its head-turning cobalt facade, and has played host to all kinds of businesses—a hospital, temple, and even a kung fu studio. It currently serves as a residence for local Hongkongers and a few businesses. Even so, you can visit the House of Stories, a free gallery and workshop space brimming with antiques, quotidian artifacts, and multimedia exhibitions. And the vibe?Nerdish curiosity. Is there a guide involved, and are they worthwhile?You'll be in great hands; the staff at House of Stories, all long-time residents of the neighborhood, are full of stories and insights. Who tends to stop in here?Blue House offers a stark contrast to the mega-modern skyscrapers and sleek bars in the surrounding area. Many travelers walk by just to snap a few shots of the vibrant facade; others linger at House of Stories to learn all about the history and architectural significance of the buildings. What's the best part of visiting the Blue HouseThe landmark building turns on a faucet of Hong Kong stories, and once you start learning about everyday life for residents in the 1920s and '30s, the more you want to know. So who would you recommend it to, and why?Architecture buffs and history lovers will enjoy Blue House for its status as one of the city's last-standing wooden tong laus, and its graceful design details. It's also a great stop for families or a worthy break from the Wan Chai bar circuit." - Kate Springer
