Mills & Chung Path - Structure 2, contrete hut, might be some storage

Hi there,

This one might have been repaired a bit. The exterior, with the exception of the roof, had been laid with granite. The roof has quite a few holes and the other time I walked by I saw a squirrel dived into it.

I hope someone could enlighten me a bit on what exactly is this structure.

I will also sent some photos later.
