It's a humble little place that is so well hidden it seems to hardly get any visitors, which is a shame because it is the only temple in Hong Kong dedicated to the God of Carpentry - Lo Pan - who has also been adopted by Chinese tradesmen (carpenters, builders and the like) in general.
As such, the main patrons of the temple appear to be those with connections to the building and construction industry. I guess the interior is much like many other temples in Hong Kong (unless you happen to be an aficionado of such things) but that's okay because the real attraction of this place is the angular roof style and the rather large expansive rooftop ceramics.
The building was constructed in 1884 and only recently celebrated its 125th anniversary. Thankfully the Antiquities and Monuments Office has given it a Grade 1 listing, but as anyone in HK will tell you this doesn't give it any protection from redevelopment. However, it seems that religious buildings are quite good at avoiding demolition in Hong Kong - everyone is too superstitious and no one wants to incur the wrath of any of the local gods by knocking down their houses!
To be honest, even if temples aren't your thing this place is well worth a visit because the local area is a real treat - very quiet and picturesque - a pleasant break from the hustle and bustle of the busy streets just a few short steps below you. I think the Govt may agree because its been included on the Central and Western heritage Trail (Part B).
