Ruinous Structure at Kau Sai Village

At the eastern end of the Kau Sai Village ( Kau Sai island, Saikung) about 40 metres beyond the pavilion there is a ruinous structure on the left hand side partially sheltered by vegetations. It is facing the Rocky Harbour to the east. Can any pill-box or war-ruin expert give me a clue about this structure ? Thanks.
