Wandering up from Chi Fu Fa Yuan the other day, towards Pok Fu Lam Reservoir. Went off a side trail I found on the first bridge over the small stream, eventually ended up at a pagoda and this blockhouse.
The blockhouse was nestled between two trenches on either side. windows, still with their rusty panels. A large rusty door also exists. The building appears more for storage than defense and is a standalone structure in the area. I also noticed large rusty hooks on either side of the building.
