At the end of Shek Tsai Po St stands the beautifully restored colonial-style Old Tai O Police Station (舊大澳警署). Built in 1902, the former marine police station was originally set up to protect the surrounding waters from pirate activity. In 2012, the restored building was reopened as the charming Tai O Heritage Hotel. Even if you aren’t staying here, it’s worth joining the free guided tour; online reservation is a must.
