Most, if not all, Tin Hau temples in Hong Kong -- like
this one at Lei Yue Mun -- are located close to the sea
But it's the rare Tin Hau temple that actually floats on the water,
Long before I moved to Hong Kong, I had heard of Temple Street (or Miu Kai, in Cantonese) -- thanks in large part to movies with titles like Queen of Temple Street and The Prince of Temple Street, as well as the Temple Street Night Market which these days is largely a tourist trap but which looked like it'd be a really cool place to visit in Derek Yee's C'est la Vie, Mon Cheri.
But it wasn't until my second visit to Hong Kong (back in the summer of 2000) that I got to realizing that -- duh! -- this Yau Ma Tei street got its name from a major temple complex in the area, whose central building is dedicated to Hong Kong's most popular goddess.
In the years since, I've come to know of the existence of a whole bunch of temples dedicated to the Taoist Goddess of the Sea (or Heavenly Queen, which her Cantonese monicker translates as), including the Tai Miu (big temple) over at Joss House Bay, others on Po Toi and Tap Mun, and in the area of Hong Kong Island that's come to be known as Tin Hau after her. And although a good number of them are no longer located near the sea (or body of water, such as Victoria Harbour), I've learnt that the vast majority of them actually originally were.
Far more unusual than the Tin Hau temples found by the sea or further inland though is a Tin Hau temple that's actually located on a boat moored at the Causeway Bay Typhoon Shelter. Home to a statue of the goddess that's believed to have been rescued from destruction during the Cultural Revolution in Mainland China, it's not been relocated elsewhere despite work on the Central-Wan Chai Bypass taking place pretty much all around it because the people in the area want it to remain where it is.
Even though few fishermen and other folks call the Causeway Bay Typhoon Shelter home any more (and the largest Tin Hau temple on Hong Kong Island lies within walking distance from it), this floating temple reputedly still remains a popular place of worship. And seemingly perenially festooned as it is with flags, it makes for quite the lively sight; with its continued existence adding color to Hong Kong's local cultural scene as far as the likes of me are concerned. :)
